Python error - IDLE's subprocess didn't ma

Question

I am new to programming and i decided to learn Python first, so;

I installed Python, latest version 3.4. and I am trying to open Python IDLE(GUI) mode, so when I open I get message "IDLE's subprocess didn't make connection. Either IDLE can't start or personal firewall software is blocking connection.".

My firewall is not problem beacuse I put Python throught it. I also tried to reinstall it and it didnt made diffirence. So please if somenone can help!

Thank you on your time :D

Answer 1

Just had the same issue. So uninstalled and reinstalled which fixed it and took 10 minutes. The key with Windows machines is delete the old directory (C:\Python27\ because windows does seem to actually delete things) and when reinstalling specify a new directory (C:\Python279\ or whatever you choose to call it).

I am using Win 10 with Python 2.7.9.

Simple...rename your .py file with some name different from any keyword name like 'random.py' which already exists in python package.

Eg. I named one file as "random.py". The same error popped up. I renamed it to "random_demo.py". It worked. The different naming discards the problem of ambiguity between an already existing file and a newly created file with same name.

Answer 3

Go to C:/Users/[your user]/AppData/Local/Programs/Python/Python35-32 and delete or rename every *.py file in this directory which is named after a certain method, function, module or library. Then run IDLE. Should work.

Hope I could help
