IndexError: list index out of range

Please help me

name = sys.argv[1] means that you most give argument from Command-line.
run.py something if you dont give argument from Commad-line you get IndexError: list index out of range
Read about sys.argv

Your code is messy.

        else: pass
    else: pass
else: pass

This is not good at all.
