I'm trying to run a program without cmd window pop-up when I double click it or when I make it exe. So I wanted to save it as .pyw extension but when I double click to script, shell can't run it. It says I need to select the program to run it or search online. How can I fix this? Windows- Python 3.4
It was okay in 3.5 when I use .pyw extension. First time I see this problem.
I always have this problem whenever I reinstall Python.
Very simple fix (at least on Windows):
1) Create a .pyw file
2) Right-click on it and select properties
3) In "Opens with:" press change
4) Navigate to your python directory and choose "pythonw.exe"

I made a Python GUI using Tkinter, but when I run it directly (double click the file) it opens the black python window but automatically closes by itself in less than half a second. I found a way to make it open the IDLE editor but it just opens the editor and doesn't run it.
I want it to run the way it runs when you open the IDLE editor and press Run Module. This runs it using Python Shell.
Is there a way I can make it automatically run using Python Shell?
Based on Mark Tolonen's comment you should do two things
rename your file to a .pyw from .py to prefer console-less runs
set your system to open .pyw files with pythonw if that's not configured already
Linux: configure xdg-open
Windows: right click and choose an application from the context menu (you may need to find where Python is installed to select the pythonw.exe executable)
Okay, one of the comments on the original question is correct.
As Terry Jan Reedy (user:722804) said,
It is possible that your mygui.py file is missing 'root.mainloop()' or the equivalent to start the GUI. IDLE lets you omit that during development so that one can interact with tkinter to retrieve values and make changes to widgets.
Adding gui.mainloop() to the end of my program worked.
i have searched on multiple forums and looks like others met similar issues but I haven't read a straightforward explanation yet. what I am trying to do is to simply open my python script by double clicking it. it used to work, but not anymore. my python scripts can still be opened via idle. and executable when it is opened and F5 pressed.
if on windows or linux, right click, open with ... select python executable, or Idle. whichever you want the default action to be.
then select the option to "always use this to open .py files"
If on a Mac, you can CTRL+Click the file, Get info > Open With and change it to Python Launcher. Click Change All. Double clicking should run the script.
Another way is to use pyinstaller which makes the script into an executable. It is pretty straightforward to use.
Change the "open with..." preference for the py files by shift + right click and choose open with from the menu. Make sure you tick the use always option
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
I want to hide the console window of a python program, so I change the file extensions to "pyw", but when I open it, the python IDLE show up even though I choose open it with "pythonw.exe"
If I use "pythonw test.py" in cmd, it works.
So I want to know what's wrong with this and how to solve this, thank you.
Change the program that opens python files.
Assuming you're using Windows, right click any python file (in your case any .pyw file, not .py), properties, change Opens with to pythonw instead of IDLE
For me, I had multiple version of Python installed that was causing issues. Once I had only had one version, I applied that pythonw.exe was the default for .pyw files and it worked.
I am running python 2.7.1. I can't figure out how to launch the IDLE IDE. I am told it comes already installed with python, but I can't find it using spotlight.
In the stock Mac OS X python installation, idle is found in /usr/bin, which is not (easily) accessible from Finder and not indexed by Spotlight. The quickest option is to open the Terminal utility and type 'idle' at the prompt. For a more Mac-like way of opening it, you'll have to create a small app or shortcut to launch /usr/bin/idle for you (an exercise left to the reader).
When you open up a new terminal window, just type in
idle
Then you will see a little rocket icon show up as IDLE loads
Then the Python shell opens up for you to edit
I think the shell command is
python -m idlelib.idle
but i am not a mac user so i can't test.
One way to run IDLE from spotlight or an icon in the Applications folder is to build a quick Automation for it. As mentioned by other commentators, this probably isn't necessary for Python 3, as it creates a shortcut automatically, and some hand-installed versions have tools to do this automatically. But if you want to roll your own:
You'll need to know the terminal command to open your version of IDLE. On my Mac right now (early 2016), running python 2.7.10, it is "idle2.7"
Using spotlight, or in the Utilities folder, open "Automator"
Choose an "Application" type document.
Make sure "Actions" is selected in the gray bar, upper left.
In the actions column, find "Run Shell Script" and double-click it, or drag it to the workflow area on the right.
Enter the terminal command in the parameters box that appears.
Save your automation (I called mine "IDLE" and put it in the Applications folder, to make it easy).
It's now available (as soon as spotlight indexes it) via all the normal methods. The only side-effect will be that while it's running, your menu bar will have a spinning gear over in the tray area next to the clock. This indicates an automation workflow is running. Once you close IDLE, it will go away.
first to launch the terminal CMD+space
second to input idle3
the idle will be activated automatically.
After you launch idle from the command line (make sure idle shell window has focus), click File, click "New File". A new window opens; this is your editor.
Type your program in the editor. Click "File", click "Save As...". Save your file somewhere with any name you choose, and a ".py" extension to the file name.
Click "Run", click "Run Module" (or, F5). Assuming no errors, the results will appear in the Shell window. Edit your file & repeat as necessary.
The answer of Matthewm1970 works like a charm!
And if you add an & to your shell command, the automation script will end immediately. There is no spinning gear. Like so:
/usr/local/bin/idle3.5&
Note the ampersand.
Cheers.

open Terminal
type "idle" and press enter
right click on "Python" icon > Options > Keep in Dock
so for python 3.4.3 in applications a folder named "python 3.4" click that and click IDLE.
for python 2.7.9 go here https://www.python.org/downloads/ and get 2.7.9 and a folder named "python 2.7" click that and click IDLE.
As to the earlier questions about starting IDLE: you can certainly start it from the command line. Also, if you installed Python using Homebrew, you can run 'brew linkapps' (from the command line); that will place an app for IDLE (among other things) in Launchpad (Applications folder).
