I am using the Remote SSH extension for VSCode. Whenever I try to run a Python file in the Python terminal using the Run Python File in Terminal command, while the terminal is already executing another python program, VSCode tries to execute the new program in the same Python terminal, instead of opening a new terminal. Is there a way to execute each python program in a new terminal so that multiple programs can run simultaneously?
Edit: Tried to open a new Python terminal explicitly, but still, the Run Python File in Terminal is always routed to the first terminal. If I run the Python program explicitly in the new terminal by typing python my_prog.py it works, but I am looking for an interactive way.
In VS Code, the command "Run Python File in Terminal" is executed by default in a "default" "Terminal", which avoids the impact of runtime confusion and reduces the time to find python and file paths at runtime.
If synchronization is required, VS Code currently does not support running two or more terminals simultaneously. You can refer to this link:
Can VSCode automatically run python scripts in two or more terminals at the same time?
If you don’t require synchronization, only need to be in a new independent terminal every time the code is executed, you can set it in "launch.json": "console": "externalTerminal",
Then click Ctrl+F5 to run the code or click F5 to debug the code:
I'd like to send code I have selected from the editor to the interpreter running in the debugging console during an active debugging session. Can I do this in VSCode? If so, how?
Update 1
While Mark (accepted answer) provided what seems to be the right command (it works for me from the contextual menu with the mouse), this isn't working for me yet as a keyboard binding, and I reported this issue here.
Update 2
This started working again as of April 21, 2020 (latest Insiders version).
See https://code.visualstudio.com/docs/python/editing#_run-selectionline-in-terminal-repl
Run Selection/Line in Terminal (REPL)
The Python: Run Selection/Line in Python Terminal command
(Shift+Enter) is a simple way to take whatever code is selected, or
the code on the current line if there is no selection, and run it in
the Python Terminal. An identical Run Selection/Line in Python
Terminal command is also available on the context menu for a selection
in the editor.
VS Code automatically removes indents based on the first non-empty
line of the selection, shifting all other lines left accordingly.
Source code that runs in the terminal/REPL is cumulative until the
current instance of the terminal is closed.
The command opens the Python Terminal if necessary; you can also open
the interactive REPL environment directly using the Python: Start REPL
command. (Initial startup might take a few moments especially if the
first statement you run is an import.)
On first use of the Python: Run Selection/Line in Python Terminal
command, VS Code may send the text to the REPL before that environment
is ready, in which case the selection or line is not run. If you
encounter this behavior, try the command again when the REPL has
finished loading.
And see Use IPython REPL in VS Code for info about the IPython REPL.
--------- generic info for other languages -------------------------------------------------------------
It sounds like you want to send it the repl. There is an unbound command:
editor.debug.action.selectionToRepl
which will send selected text to the debug repl.
{
"key": "alt+y", // whatever you want here
"command": "editor.debug.action.selectionToRepl"
},
No, you cannot send a selection of code to the debugger. You need to debug the whole file or use the Interactive Window support to debug a specific cell.
To run a file via the SublimeREPL plugin, I select 'Tools' -> 'SublimeREPL' -> 'Eval In REPL' -> 'File'
When I select 'File' nothing happens. How do I configure Sublime Text 2 to use a specified REPL ?
I think SublimeREPL only supports this for python files, if you look here you'll see that it is only under the python heading that this feature is mentioned.
Python
Launch python in local or remote(1) virtualenv.
Quickly run selected script or launch PDB.
Use SublimeText2 Python console with history and multiline input.
Besides if you press(on windows) shift+ctrl+p you'll see that if you type repl current it will say:
SublimeREPL: Python - RUN Current File
As the only alternative, well except for PDB.
As #daniel-figueroa states, SublimeREPL only runs Python code as far as I'm aware.
If you are just trying to run Python with SublimeREPL, try:
Tools -> SublimeREPL -> Python -> Python -> RUN current file
Alternatively, if you're actually intending to evaluate with SublimeREPL, the plugin author, #wuub explains and offers a solution HERE.
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:
