IDLE's subprocess didn't make a connection. Either IDLE can't start or personal firewall software is blocking connection

Question

I have tried uninstalling it and have searched other answers. None of them have worked; IDLE opens, but I can't run anything I write.

Solution

In Windows 10 1. Type in "Controlled folder Access" 2. Select "Allow an app through Controlled folder access" Select yes to "UAC" 3. Click on "+ Add an allowed app" 4. Select "recently blocked apps" 5. Find the executable for the C:\Python27 6. Click the + to add it. 7. Select Close Then try running the Python Shell again. This worked for me 100%

Also, add exception through Windows Firewall Python27 select Private and Public.

in a console "python -m idlelib -n" (idlelib.idle on 2.7)

#2 was the cause of problem for me. Deleted 'string.py', 'string.pyc' from "C:\Python27" and the problem was fixed.
