https://medium.com/never-too-late-to-machine-learn/how-to-step-by-step-setup-notepad-to-run-python-scripts-e1ce3b3ac7fe
I am reading from this tutorial linked above.
What I am doing is trying to run python for the first time on Notepad++. I've downloaded python, etc.
What I am lost on is this:
"Just copy the location of the python exe file, and let’s go back to Notepad++. The execute screen is waiting for us.
In the execute screen, paste the location of Python followed with “$(FILE_NAME)” "
What is the execute screen, where am I pasting the location to?
I hope someone can help me. Thank you.
first, you need "$(FULL_CURRENT_PATH)" for full path of file, the $(FILE_NAME) is for file name only or relative path
then you can paste like
C:\Python39\python.exe "$(FULL_CURRENT_PATH)"
for execute screen, new name for the menu is Execute NppExec Script.. see image below
to run your python script in notepad++ is quite simple:
make sure your python is correctly installed, open your console and type python, you should see something similar to the following (it should say Python X.Y.Z accordingly to the version you have installed)
now that we know that python is correctly installed, go to notepad++, open on it your desire script and go to the Run menu and select Run...
enter the following command python -i "$(FULL_CURRENT_PATH)" and press Run
You should see the following
And that is all.
-
Now that the previous worked, lets make it more reusable, repeat step 1 and 2, but instead of Run press Save..., give it a name (like python for example) and if you so desire also a keyboard binding (a key combination to press to run this command)
Now in step 1, you can pick python (or whatever you name it) instead or "Run..." to run you script (or press you key combination if you give it one)
now some additional explanation about the previous command python -i "$(FULL_CURRENT_PATH)"
the -i option is to enter in interactive mode, that is run you script and then continue executing python so you can do more python stuff with everything for your script loaded in there too, that way the console doesn't just close intermediately after your script is done running.
$(FULL_CURRENT_PATH) is a command for notepad++ to said to substitute there for the full path of your given script
Alternative command: cmd /K CD "$(CURRENT_DIRECTORY)" & python -i "$(FILE_NAME)"
This command is the equivalent to opening your console (cmd /K), move with cd to the folder where your script is (CD "$(CURRENT_DIRECTORY)") and then run your script with python in interactive mode (python -i "$(FILE_NAME)") and & is to separate both instructions (the /K is like python's -i but for the console) (the "-i" is now optional, but I prefer it with it to test other stuff in the script without need to put it on the script because doing so make little sense...)
Why you might want to use this over the other? two reason:
the first is when dealing files so you don't have to type the full path of a given file that sit next to your script so you can use just the name of said file, aka set the working directory to that where the script is located, otherwise it will be that where notepad++ is located (usually it might be like "C:\Program Files\Notepad++").
In case of an error, the windows will remain open so you can know what was the error instead of closing abruptly.
I'm trying to run a python script using Notepadqq in Ubuntu, but when I try running my script by going to the Run command it oop up a windows that says
Special Placeholders
with the options to save or OK and cancel. See image
I think like that:
/usr/bin/python3 %path%
This window allows you to have several previously configured commands. For example, you can create one command to execute the default python2.7 (/usr/bin/python2.7), another one to execute with python3 (/usr/bin/python3), or perhaps a specific virtual environment python (let's say /home/py3env/bin/python).
Natively, notepadqq won't know you want to execute it with python. At the blank space, write the following command (edit python path if needed):
gnome-terminal -x sh -c '/usr/bin/python3 %path%'
After that, click the "Save" button. You will be asked to enter a name for the command (e.g. "run default python3"). After this, you can run your python scripts by clicking on you named command.
If you need the terminal to be kept open after the command is executed, you can edit your terminal preferences. Open a terminal and follow this path:
(edit -> preferences -> go to your profile -> "Command" tab -> When commands exits -> Hold the terminal open)
gnome-terminal-preferences
I use two "Run" shortcuts.
This runs the code and holds the xterm open so I can see the output. Handy if there's an error.
/usr/bin/xterm -hold -e /usr/bin/python3 %path%
And to auto close the xterm.
/usr/bin/xterm -e /usr/bin/python3 %path%
Make sure to save your file because this works with the file on the disk at %path%
Also you can change /usr/bin/xterm to point to whatever term you like.
Running the code depends on the console you want to use. Since the question asks for a Ubuntu solution I'd suggest gnome-terminal.
gnome-terminal -e "python3 %path%"
Here's a screenshot and sample code for clarity. The last line input() prevents the window from closing so the user can view the output. I've tried this solution with Ubuntu 20.04.
I have set F2 prompt key with map <f2> :w<cr>:! D:\Python34\python %<cr>,when i open an python file in vim and press F2,the python file will be executed .For a simple example,
here is my python file and opened in gvim .
Now i can't input other python lines ,only thing i can do is to see the result and hit any key to close this window.
What i want is :
when i press F2, (the python file was opened in gvim) ,the python console pop up,and all the files in the python file were copied into the python console automatically,and i can go no to input some lines such as Obj().hello in the python console or go on to edit in gvim ,i am a lazy man ,the gvim and python console all opened waiting to serve me , can i write a vim scripts to achieve the target?
The command :!D:\Python34\python -i % works fine ,i got the ouput
There is still a problem remain,
1)when command :!D:\Python34\python -i % works ,the gvim window will be frozen , i can't drag my mouse to see codes in vim.
2)there is no any python codes in the python console wiondow
So if the program is full of many lines ,and i can't remember the previous content ,worse still， the gvim window frozen ,how can i get the codes?
Avoid blocking
To make the call asynchonous (to avoid that GVIM is blocked during the Python session), use the Windows-specific :!start command:
nnoremap <f2> :w<cr>:!start D:\Python34\python -i %<cr>
List teh codez
I don't know whether it is possible to list the passed source code from the interactive Python debugger. But you can print the file contents before starting it:
nnoremap <f2> :w<cr>:!start cmd /c type % && D:\Python34\python -i %<cr>
Additional tips
You should use :noremap; it makes the mapping immune to remapping and recursion.
As your mapping only works correctly from normal mode, use :nnoremap (or extend it to support visual-mode selections, too).
Maybe Vim plugin Conque will solve your problem:
Installation instrucions are here https://code.google.com/p/conque/
To use just type :ConqueTermVSplit python -i test.py (VSplit is for vertical split - you may use horizontal)
There is no blocking of your window with python code - you may escape interactive mode and switch to your window with Ctrl+W twice
You could approach the problem from the Python angle (2.7).
Keep the file where it is (or save it with some unique name to a temporary directory) and have python load the file directly.
Go to that location in your shell and run python interactively (or have vim spin off an interpreter for you)
Import your file import demo
Experiment with what you have implemented demo.SomeModule().meth()
Make some changes in vim
Reload your python module reload(demo)
Experiment with your code again demo.SomeModule().differentMeth()
You can also have vim create a file with shortcut functions for loading/reloading the file you are working on. When vim kicks off the interpreter, you can have it set this file to the PYTHONSTARTUP environment variable, which is a file the interpreter will automatically load when it starts up. For example, you could have a function called r() to automatically reload the file you are working on.
It's also worth mentioning that reloading modules can be a little weird. If you instantiate some modules then reload the file, only new modules will use the new code; the old modules will run with the old code.
We are using Ubuntu for OpenERP development, everyday at morning I have to browse to openERP directory from terminal, start the "openerp-server" python file with lots of parameters, and then keep the terminal window open.
Is there a way that I can double click a python file on desktop which will start the following file with its parameters from its own directory ?
The directory I use right now to start the program is "home/username/Projects/openerp_7_0/server/"
after navigating to this path in terminal I enter:
"python openerp-server --addons-path=../addons "
So how can I create a shortcut for this on desktop.
Rather than “double clicking a python file on desktop” you could put a shell script on the desktop (and single click to start, not double click), somewhat as follows.
#!/bin/sh
cd $HOME/Projects/openerp_7_0/server/
/usr/bin/xterm -e 'python openerp-server --addons-path=../addons; /bin/bash' &
(Alternately, say /usr/bin/gnome-terminal instead of /usr/bin/xterm.) The ; /bin/bash part may be unnecessary if the openerp-server runs indefinitely. Include the ; /bin/bash part if you want the terminal to remain (and display any output) when openerp-server finishes; don't include it if you want the terminal to go away when openerp-server finishes.
Although I would recommend trying to import the python file and then running it that way, I get the feeling that in this case you can't.
So you could try something like this.
import os
os.system('python /home/username/Projects/openerp_7_0/server/openerp-server --addons-path=../addons')
I prefer using Notepad++ for developing,
How do I execute the files in Python through Notepad++?
First option: (Easiest, recommended)
Open Notepad++. On the menu go to: Run -> Run.. (F5). Type in:
C:\Python26\python.exe "$(FULL_CURRENT_PATH)"
Now, instead of pressing run, press save to create a shortcut for it.
Notes
If you have Python 3.1: type in Python31 instead of Python26
Add -i if you want the command line window to stay open after the script has finished
Second option
Use a batch script that runs the Python script and then create a shortcut to that from Notepad++.
As explained here: http://it-ride.blogspot.com/2009/08/notepad-and-python.html
Third option: (Not safe)
The code opens “HKEY_CURRENT_USER\Software\Python\PythonCore”, if the key exists it will get the path from the first child key of this key.
Check if this key exists, and if does not, you could try creating it.
#Ramiz Uddin's answer definitely deserves more visibility :
Open Notepad++
On the menu go to: Run → Run.. (F5)
Type in: cmd /K python "$(FULL_CURRENT_PATH)"
Here is what's worked for me:
Open notepad++ and press F5. You'll get a little popup box:
Type: C:\Python27\python.exe -i "$(FULL_CURRENT_PATH)" for Python 2.7.
and then Save As..., and pick your own key combo to start it each time you want to run something
I also wanted to run python files directly from Notepad++.
Most common option found online is using builtin option Run. Then you have two options:
Run python file in console (in Windows it is Command Prompt) with code something like this (links: ):
C:\Path\to\Python\python.exe "$(FULL_CURRENT_PATH)"
(If your console window immediately closes after running then you can add cmd /k to your code. Links: ) This works fine, and you can even run files in interactive mode by adding -i to your code (links: ).
Run python program in IDLE with code something like this (links: , in these links C:\Path\to\Python\Lib\idlelib\idle.py is used, but I am using C:\Path\to\Python\Lib\idlelib\idle.bat instead, because idle.bat sets the right current working directory automatically):
C:\Path\to\Python\Lib\idlelib\idle.bat "$(FULL_CURRENT_PATH)"
Actually, this doesn't run your program in IDLE Shell, but instead it opens your python file in IDLE Editor and then you need to click Run Module (or click F5) to run the program. So it opens your file in IDLE Editor and then you need run it from there, which defeats the purpose of running python files from Notepad++.
But, searching online, I found option which adds '-r' to your code (links: ):
C:\Path\to\Python\Lib\idlelib\idle.bat -r "$(FULL_CURRENT_PATH)"
This will run your python program in IDLE Shell and because it is in IDLE it is by default in interactive mode.
Problem with running your python files via builtin Run option is that
each time you run your python file, you open new console or IDLE window and lose all output from previous executions. This might not be important to some, but when I started to program in python, I used Python IDLE, so I got used to running python file multiple times in same IDLE Shell window. Also problem with running python programs from Notepad++ is that you need to manually save your file and then click Run (or press F5). To solve these problems (AFAIK*) you need to use Notepad++ Plugins. The best plugin for running python files from Notepad++ is
NppExec. (I also tried PyNPP and Python Script. PyNPP runs python files in console, it works, but you can do that without plugin via builtin Run option and Python Script is used for running scripts that interact with Notepad++ so you can't run your python files.) To run your python file with NppExec plugin you need to go to Plugins -> NppExec -> Execute and then type in something like this (links: ):
C:\Path\to\Python\python.exe "$(FULL_CURRENT_PATH)"
With NppExec you can also save your python file before run with npp_save command, set working directory with cd "$(CURRENT_DIRECTORY)" command or run python program in interactive mode with -i command. I found many links ( ) online that mention these options, but best use of NppExec to run python programs I found at NppExec's Manual which has chapter 4.6.4. Running Python & wxPython with this code:
npp_console - // disable any output to the Console
npp_save // save current file (a .py file is expected)
cd "$(CURRENT_DIRECTORY)" // use the current file's dir
set local #exit_cmd_silent = exit() // allows to exit Python automatically
set local PATH_0 = $(SYS.PATH) // current value of %PATH%
env_set PATH = $(SYS.PATH);C:\Python27 // use Python 2.7
npp_setfocus con // set the focus to the Console
npp_console + // enable output to the Console
python -i -u "$(FILE_NAME)" // run Python's program interactively
npp_console - // disable any output to the Console
env_set PATH = $(PATH_0) // restore the value of %PATH%
npp_console + // enable output to the Console
All you need to do is copy this code and change your python directory if you use some other python version (e.g.* I am using python 3.4 so my directory is C:\Python34). This code works perfectly, but there is one line I added to this code so I can run python program multiple times without loosing previous output:
npe_console m- a+
a+ is to enable the "append" mode which keeps the previous Console's text and does not clear it.
m- turns off console's internal messages (those are in green color)
The final code that I use in NppExec's Execute window is:
npp_console - // disable any output to the Console
npp_save // save current file (a .py file is expected)
cd "$(CURRENT_DIRECTORY)" // use the current file's dir
set local #exit_cmd_silent = exit() // allows to exit Python automatically
set local PATH_0 = $(SYS.PATH) // current value of %PATH%
env_set PATH = $(SYS.PATH);C:\Python34 // use Python 3.4
npp_setfocus con // set the focus to the Console
npe_console m- a+
npp_console + // enable output to the Console
python -i -u "$(FILE_NAME)" // run Python's program interactively
npp_console - // disable any output to the Console
env_set PATH = $(PATH_0) // restore the value of %PATH%
npp_console + // enable output to the Console
You can save your NppExec's code, and assign a shortcut key to this NppExec's script. (You need to open Advanced options of NppExec's plugin, select your script in the Associated script drop-down list, press the Add/Modify, restart Notepad++ , go to Notepad++'es Settings -> Shortcut Mapper -> Plugin commands, select your script, click Modify and assign a shortcut key. I wanted to put F5 as my shortcut key, to do that you need to change shortcut key for builtin option Run to something else first.) Links to chapters from NppExec's Manual that explain how to save you NppExec's code and assign a shortcut key: NppExec's "Execute...", NppExec's script.
P.S.*: With NppExec plugin you can add Highlight Filters (found in Console Output Filters...) that highlight certain lines. I use it to highlight error lines in red, to do that you need to add Highlight masks: *File "%FILE%", line %LINE%, in <*> and Traceback (most recent call last): like this.
First install Python from https://www.python.org/downloads/
Run the installer
** IMPORTANT **
Be sure you check both :
Install launcher for all users
Add Python 3.6 to path
Click install now and finish the installation.
Open notepad++ and install plugin PyNPP from Plugin Manager. I'm using N++ 6.9.2
Save a new file as new.py
Type in N++
import sys
print("Hello from Python!")
print("Your Python version is: " + sys.version)
Press Alt+Shift+F5
Simple as that.
On the menu go to: "Run" --> "Run..." (or just press F5).
For Python 2 type in:
py -2 -i "$(FULL_CURRENT_PATH)"
For Python 3 type in:
py -3 -i "$(FULL_CURRENT_PATH)"
References:
To understand the py command better:
py -h

Thanks to Reshure for his answer that got me on the right track to figure this out.
All the answers for the Run->Run menu option go with the "/K" switch of cmd, so the terminal stays open, or "-i" for python.exe so python forces interactive mode - both to preserve the output for you to observe.
Yet in cmd /k you have to type exit to close it, in the python -i - quit(). If that is too much typing for your liking (for me it sure is :), the Run command to use is
cmd /k C:\Python27\python.exe "$(FULL_CURRENT_PATH)" & pause & exit
C:\Python27\python.exe - obviously the full path to your python install (or just python if you want to go with the first executable in your user's path).
& is unconditional execution of the next command in Windows - unconditional as it runs regardless of the RC of the previous command (&& is "and" - run only if the previous completed successfully, || - is "or").
pause - prints "Press any key to continue . . ." and waits for any key (that output can be suppressed if need).
exit - well, types the exit for you :)
So at the end, cmd runs python.exe which executes the current file and keeps the window opened, pause waits for you to press any key, and exit finally close the window once you press that any key.
None of the previously proposed solutions worked for me. Slight modification needed.
After hitting F5 in Notepad++, type:
cmd /k "C:\Python27\python.exe $(FULL_CURRENT_PATH)"
The command prompt stays open so you can see the output of your script.
I use the NPP_Exec plugin (Found in the plugins manager). Once that is installed, open the console window (ctrl+~) and type:
cmd
This will launch command prompt. Then type:
C:\Program Files\Notepad++> **python "$(FULL_CURRENT_PATH)"**
to execute the current file you are working with.
I wish people here would post steps instead of just overall concepts. I eventually got the cmd /k version to work.
The step-by-step instructions are:
In NPP, click on the menu item: Run
In the submenu, click on: Run
In the Run... dialog box, in the field The Program to Run, delete any existing text and type in: cmd /K "$(FULL_CURRENT_PATH)"
The /K is optional, it keeps open the window created when the script runs, if you want that.
Hit the Save... button.
The Shortcut dialogue box opens; fill it out if you want a keyboard shortcut (there's a note saying "This will disable the accelerator" whatever that is, so maybe you don't want to use the keyboard shortcut, though it probably doesn't hurt to assign one when you don't need an accelerator).
Somewhere I think you have to tell NPP where the Python.exe file is (e.g., for me: C:\Python33\python.exe). I don't know where or how you do this, but in trying various things here, I was able to do that--I don't recall which attempt did the trick.
My problem was, as it was mentioned by copeland3300, that my script is running from notepad++ folder, so it was impossible to locate other project files, such as database file, modules etc. I solved the problem using standard notepad++ "Run" command (F5) and typing in:
cmd /k "cd /d "$(CURRENT_DIRECTORY)" & python "$(FULL_CURRENT_PATH)""
Python WAS in my PATH. Cmd window stayed open after script finished.
No answer here, or plugin i found provided what i wanted. A minimalist method to launch my python code i wrote on Notepad++ with the press of a shortcut, with preferably no plugins.
I have Python 3.6 (64-bit), for Windows 8.1 x86_64 and Notepad++ 32bit. After you write your Python script in Notepad++ and save it, Hit F5 for Run. Then write:
"C:\Path\to\Python\python.exe" -i "$(FULL_CURRENT_PATH)"
and hit the Run button. The i flag forces the terminal to stay still after code execution has terminated, for you to inspect it. This command will launch the script in a cmd terminal and the terminal will still lie there, until you close it by typing exit().
You can save this to a shortcut for convenience (mine is CTRL + SHIFT + P).
I would like to avoid using full python directory path in the Notepad++ macro. I tried other solutions given in this page, they failed.
The one working on my PC is:
In Notepad++, press F5.
Copy/paste this:
cmd /k cd /d "$(CURRENT_DIRECTORY)" && py -3 -i "$(FULL_CURRENT_PATH)"
Enter.
There is one issue that I didn't see resolved in the above solutions. Python sets the current working directory to wherever you start the interpreter from. If you need the current working directory to be the same directory as where you saved the file on, then you could hit F5 and type this:
cmd /K cd "$(CURRENT_DIRECTORY)"&C:\Users\username\Python36-32\python.exe -i "$(FULL_CURRENT_PATH)"
Except you would replace C:\Users\username\Python36-32\python.exe with whatever the path to the python interpreter is on your machine.
Basically you're starting up command line, changing the directory to the directory containing the .py file you're trying to run, and then running it. You can string together as many command line commands as you like with the '&' symbol.
Extending Reshure's answer
Open Run → Run... from the menubar in Notepad++ (shortcut: F5)
In the given space, enter:
"$(FULL_CURRENT_PATH)" -1
Click Run
ta da!
I started using Notepad++ for Python very recently and I found this method very easy. Once you are ready to run the code,right-click on the tab of your code in Notepad++ window and select "Open Containing Folder in cmd". This will open the Command Prompt into the folder where the current program is stored. All you need to do now is to execute:
python
This was done on Notepad++ (Build 10 Jan 2015).
I can't add the screenshots, so here's a blog post with the screenshots - http://coder-decoder.blogspot.in/2015/03/using-notepad-in-windows-to-edit-and.html
In Notepad++, go to Run → Run..., select the path and idle.py file of your Python installation:
C:\Python27\Lib\idlelib\idle.py
add a space and this:
"$(FULL_CURRENT_PATH)"
and here you are!

In case someone is interested in passing arguments to cmd.exe and running the python script in a Virtual Environment, these are the steps I used:
On the Notepad++ -> Run -> Run , I enter the following:
cmd /C cd $(CURRENT_DIRECTORY) && "PATH_to_.bat_file" $(FULL_CURRENT_PATH)
Here I cd into the directory in which the .py file exists, so that it enables accessing any other relevant files which are in the directory of the .py code.
And on the .bat file I have:
#ECHO off
set File_Path=%1
call activate Venv
python %File_Path%
pause
You can run your script via cmd and be in script-directory:
cmd /k cd /d $(CURRENT_DIRECTORY) && python $(FULL_CURRENT_PATH)
I usually prefer running my python scripts on python native IDLE interactive shell rather than from command prompt or something like that. I've tried it, and it works for me. Just open "Run > Run...", then paste the code below
python -m idlelib.idle -r "$(FULL_CURRENT_PATH)"
After that, you can save it with your hotkey.
You must ensure your desired python is added and registered in your environment variables.
In addition to the many other answers about using a system-wide installation of a Python interpreter, there is also a Python plugin for Notepad++. I've used it many times, and it works quite well. You can even assign shortcut keys to run specific Python scripts.
It is open-source and gratis (free of charge).
The source code and plugin are located here:
https://github.com/bruderstein/PythonScript/
