My OS is Mac 10.10.5

I have successfully installed Python 2.6.0b2 on this computer.

I have used Python 2.7 before on this computer but now I get this error:

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

Picture of the error: (Picture of error) Left is Python 2.7, right is Python 3.6

I faced this problem few days back. I saved a program i was working with as threading.py that clashed with standard python module files.

See if you have a .py that is saved same or similar name as python modules and rename / delete it. Especially something latest that you worked on.

  • I deleted all the .py files I have and still hasn't worked. I don't know what I need to do now... – James Lawrence Oct 22 '16 at 11:11
  • Did u clean from python folders as well as folders you work from? Also. While IDLE may not work, command line execution should work. – Anil_M Oct 22 '16 at 16:09
