python file executables

Question

I have python 3.2 and 2.7 both installed. When i tried to run filename.py command prompt opened for a second and disappeared, and nothing run. I also have problem running from the idle for python. Maybe it is because of the environment variable? Please help.

Answer 1

First, do you have something like input("THE END") or os.system("pause") at the end of your script ? With this, the prompt should not dissapear and you may see what is wrong.

For your executable, you should avoid the problem by typing the full path for the Python interpreter you want to use :

MyPrompt> C:\Python32\python.exe filename.py
