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

Delete all newely created .py files in the directory with Python. for example random.py, end.py - that was my problem that caused the same notification window. Reason in filename conflicts.
