I remember that at some point I used to be able open up the python IDLE from the command line by simply typing "idle" return, which would pop up the python idle editor. I recently got a new machine and installed python, but have to open idle from the windows start menu.
When trying to run "idle" or "idle3" from the command line I get
C:\Users\SSims>idle3
'idle3' is not recognized as an internal or external command,
operable program or batch file.
Can anyone tell me how to get the command line "idle" command set up. Thanks for any help!
There are no step-by-step fixes that I have found online to answer this question, but many that answer specific portions of the question scattered around online. Hopefully, this will help others with the same question in the future, as I know there are many who could benefit from this answer.
If you have selected "Add Python X.x to Path Variables" upon installation then you should be able to run "python" from the command line to start the python editor. Similarly, this will allow you to do the same for IDLE.
First, hit your windows key and type "path" then enter to go to your system environment page in settings.
Next, click "Environment Variables then select "Path" under user variables
There should be a popup that contains a path that looks like this:
C:\Users\SSims\AppData\Local\Programs\Python\Python37-32\
Copy that address then click "new"
Paste that address, then at the end of it type "Lib\idlelib" so that your new variable now looks like:
C:\Users\SSims\AppData\Local\Programs\Python\Python37-32\Lib\idlelib
This should be the path to the folder in which the idle executable file resides.
Note: You can check that path to ensure it is right by pasting it into the windows start menu and it should redirect you to the folder. If it doesn't, you can paste the path to the python folder from earlier that was added automatically upon installation and search around in there until you find the idle executable, then add that folder to the Path variables to get it to work.
You should now be able to run the idle command from command prompt, hope this helps!!
Instead of IDLE use, python -m idlelib command
check the IDLE official document

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 am new to VScode and want to run Python in it for my college project. I have seen that in VScode all the programmes are executed in Windows PowerShell Terminal(By default). But the problem is that it also shows the file address which is being executed which I don't want. So, please could you give a suggestion which software should be used in the terminal which only executes code and doesn't show any file address. And How can I change it?
VS code supports multiple shells. By default it's powershell (PS >) on windows
Click on "Select Default Profile" to change it (And restart VS code) or you can directly click on any of the available shells (shown in below pic).
About hiding the "file address" - you can always change the shell's corresponding settings file which it reads on load.
Ex: bash shell uses .bashrc settings file. And how to hide file path could be checked here for bash : Show only current directory name (not full path) on bash prompt
Similarly check how it's done for the shell you want
You can try the extension of Code Runner, it will be like this:
Otherwise, you can change the value of "console" in the launch.json file to the internalConsole, then run the python file in the debug mode(F5), it will be like this:
ctrl+shift+ is a Command Used to open terminal in VS code .. You can also Try Extension of python shell or powershell in VSCode ...
Everytime I run python file at vscode(in this case I press Run python File in Terminal button), terminal is opened as Powershell always.
my select default profile settings are command prompt. so when I open a new terminal, it opens with cmd. However, when I run the python file even though the cmd terminal is open, a new powershell terminal is launched. and I don't know why...
How do i fix it ?
Yeah, it's an issue of VSCode In version v1.60.0. You can refer to GitHub issue #132150 for more details.
There are a lot of people report this kind of problem recently.
And the only workaround to this problem is to roll back the version to v1.59 until the release of v1.60.1 for now.
There might be an issue in your select default profile settings. However, you can always choose a default shell by pressing ctrl + ~ (~ tilda key) You can open up a shell in vscode, as seen below. By default this might open up powershell, from there you can select your default shell.
Note: Some of the options seen in the image require WSL2 (Windows Subsystem for Linux) to be installed and activated on any Windows system. Clicking any of those options will open a new tab of that shell, but if you click on the '+' plus button or restart vscode later, it will go back to the default shell (powershell) in our case.
Now click the option on the bottom that says select default profile
And you should see a window like this:
From there you can select the default shell in this window. And these changes will be saved, so anytime you click the '+' plus button to open a new shell instance, or relaunch vscode it will open your selected shell choice by default.
And that's it! From here you can select cmd since you want that to be your default shell. And you should be good to go. You can change these settings at anytime, by following these steps again.
Since you're using Python. I suggest using powershell for one reason. You can use a tool known as chocolatey which is like a package manager for windows that can download, install/update, and most importantly set environment variable paths in windows automatically. Which might be a lot easier than doing it manually on cmd.
To run the python script you can do the following:
$ python /path/to/file.py
If you want to run your python file in the terminal with cmd then you just open a new terminal and type the command
python "path/to/file.py"
If it doesn't work try using
py "path/to/file.py"
I am practicing python code and executing it through command line. each time i have to execute my python file i go to cmd and write
D:\PythonPractice>python myClass.py
Is there any standard and comfortable way available to execute python code quickly?
If you are executing the same command, with no changes to arguments or anything, you can pack it in a .bat file (windows executable)
Name it something like myscript.bat
D:\PythonPractice>python C:\path\to\myClass.py
Put full path inside it. Now double click will do.
Use PyCharm Software by JetBrains (same company who developed Android studio and Kotlin language), it will help you in many ways .
Run Python with single press of a button.
Add modules easily just with some clicks.
Debugging the code as smooth as possible.
It is Awesome, I am using it for past couple of months.
you can change file association which controls what to do when invoking filename in command line. For instance, when you just type text filename in cmd, notepadd will be opened, for word docs Word or other document editor.
Have a look into following link from google or you can fiddle by yourself starting from Control Panel > Control Panel Home > Default Programs > Set Associations. Select a file type in the list and click Change Program.
Alternatively,you can use any of Python IDE (PyCharm,PyDev etc.) so you will be able to run directly scripts from editor.
With Notepad++, you can also create a shortcut to be able to launch your python script :
Menu Run > Run (or press F5)
Choose the python .exe (default in C:\Program Files (x86)\Python36-32\python.exe
Then add this code next to the path : "$(FULL_CURRENT_PATH)"
This will allow to execute the current file
example of command with Python 3.6 :
"C:\Program Files (x86)\Python36-32\python.exe" "$(FULL_CURRENT_PATH)"
Then save the command, by assigning a shorcut key, it's better with a modifier like SHIFT (SHIFT + F10)
Now you can launch any script with this shortcut.
I have Python 2.7.5 that installed with ArcGIS 10.2.2. When I first right-clicked a .py script I'd previously written it listed the "Edit with IDLE" option in the context menu. However, this option no longer appears when I right-click a .py file.
I have read numerous threads concerning this issue and attempted some of them, such as modifying/removing registry keys and then reinstalling/repairing the software. I am not interested in using an IDE at this point, though many will be happy to know I intend to use an IDE later on. Right now, the purpose is to fix the problem rather than avoid and work around it.
I appreciate the help I've gotten from the online community in the past, and I'm confident someone will come through with a solution for me.
How do I get "Edit with IDLE" back in the context menu?
Most of the time when this problem occurs, people will read answers directing them into the windows registry, often unnecessarily.
In the majority of cases, the registry key
HKEY_CLASSES_ROOT\Python.File\shell\Edit with IDLE\command
will already exist and have the correct value, but it will only be used by Windows shell context menu if .py files are set by default to open with python.exe.
This is the first thing to check, and solves the problem in the majority of cases:
right click on a .py file
open with...
choose default program...
tick always use the selected program to open this kind of file
choose python.exe
This runs the script in a terminal, but also sets the filetype back to python.
Now check the right click menu again.
As a newer update, for people that are having the "missing idle" issue with Windows 10 using Python 3.6 (64-bit).
From my experience, this happens when you install other python editors, and you change your default app to open with that editor.
The easiest way to fix this issue is to click the "start" button, then navigate to settings --> System --> Default Apps --> "Choose default apps by file type". Scroll down till you find ".py" file type and click on the icon and choose "Python"(has a little rocket ship in the icon). This will change your default app back to "Python.exe", and the context menu "edit with idle" will appear once again on your ".py" files.
Hope this helps!

Here's a reg file to add the command to edit with IDLE for Python.File (.py) and Python.NoConFile (.pyw) file types. It's for Python 2.7, installed in C:\Python27, so substitute the paths to pythonw.exe and idle.pyw that are relevant to your installation. Save it to a .reg file. Then right-click and choose Merge.
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\Python.File\shell\Edit with IDLE\command]
#="\"C:\\Python27\\pythonw.exe\" \"C:\\Python27\\Lib\\idlelib\\idle.pyw\" -e \"%1\""
[HKEY_CLASSES_ROOT\Python.NoConFile\shell\Edit with IDLE\command]
#="\"C:\\Python27\\pythonw.exe\" \"C:\\Python27\\Lib\\idlelib\\idle.pyw\" -e \"%1\""
Another option would be to just open the file with the idle by choosing open with:
C:\Python27\ArcGIS10.3\Lib\idlelib\idle.bat
as the default program.
I got the "Edit with IDLE" back with the option "Repair" of the deinstallation-menu.
Adding a little more detail to Teodorico Levoff's answer for those who need a little more explanation, like myself.
Open a text editor, such as Notepad, and copy/paste the following, but be sure to modify the paths to pythonw.exe and idle.pyw so that they match the paths in your own system:
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\Python.File\shell\Edit with IDLE\command]
#="\"C:\Python27\pythonw.exe\" \"C:\Python27\Lib\idlelib\idle.pyw\" -e \"%1\""
[HKEY_CLASSES_ROOT\Python.NoConFile\shell\Edit with IDLE\command]
#="\"C:\Python27\pythonw.exe\" \"C:\Python27\Lib\idlelib\idle.pyw\" -e \"%1\""
Save this text file as idle.reg in the Python27 folder, so you now have a file that resembles this (with your own file path, of course):
C:\Python27\idle.reg
Right-click the idle.reg file, and in the context menu, click Merge. A couple instructions may appear or notices that require a Yes or Continue that I selected. In the end, my .py files give me the option to "Edit in IDLE" again.
I hope these explanations are helpful. Big thank you to those who've solved this problem before and shared there solutions.
For opening your file in IDLE mode or in python exe mode u can follow this simple steps. Works for me in my windows 7 system.
For IDLE mode:
Select the file and press right mouse
press open with---->choose default program
press browse and go to the folder where your python programm is installed
in python folder search IDLE and select the batch file
press open and your file will be open in IDLE edit mode
For python.exe mode:
In command prompt write "where python"
copy the path from cmd
Select the file and press right mouse
press open with---->choose default program
press browse and go to the selected path
press open and your file will be open in IDLE edit mode
As click to save button to save your python code there will be Two Extensions...1) .py and 2) .pyw.
So for Python 2 you have to save python program using extension .pyw.
I think the majority of cases are caused by the Py launcher that comes with Python 3. When you install Python 3 alongside Python 2.x, the *.py and *.pyw files are associated to run with the new Py launcher. Since *.py and *.pyw files are no longer associated with Python.exe, that breaks the "Edit with IDLE" and similar context menu options, despite all relevant registry entries being present and correct.
Right clicking a file and choosing Python.exe and selecting "always use the selected program to open this kind of file" option fixes the problem (even if Python.exe seems to be already set as the default program) but then you lose the Py launcher functionality. This may well be considered a bug with the Python 3.x installer and I think should be fixed at that level by the Python developers.
Meanwhile, I'm sure registry wizards can find a workaround for this but unfortunately, that's beyond me at the moment.
I followed Teodorico Levoff's directions above, as well as Abyx's from the following page:
https://superuser.com/questions/280636/trying-to-edit-a-python-file-but-the-edit-with-idle-has-disappeared-when-i-rig
However, it only works partially. When I right-click on a .py file, no 'Edit with IDLE' shows up. Choosing 'Edit' opens the file with IDLE. Also, the python icon is not associated with .py files. I decide to associate it with Notepad, then associate it with Python again. That works the magic. The icon is back, and so is the 'Edit with IDLE' option. Hope it helps.
This issue is arising because of the problem in the registry of Python installation. While one may edit the registry and resolve the issue, the simple solution for this can be:
DELETE ALL THE REGISTRIES pertaining to the py extensions and
Re-install Python and let installation take its course of action.
The problem will definitely resolve.
Happy Programming
After uninstalling both 2.7 and 3.6, reinstalling 3.6, I ran the init.py ,main.py, and idle.pyw found in C:\Program Files\python\Lib\idlelib and the edit with menu reappeared
