[Python 3][resolved] IDLE's subprocess didn't make connection. Either IDLE can't start a subprocess or personal firewall software is blocking the connection

1) Check is your file name same as the module you want input, if yes, rename that.

 

 2) close your IDLE and python spell and kill all process named pythonw.exe,

If the problem still exists after doing that, you can move the project away or rename the directory.
