Using python method in other program

[Alex Frieder]

I'm new at Python. I created a program that (for example) prints the number.
So test.py is:

def a(b):
    print b

Now I have a program use.py and I want to use a() in it. How would I go about importing it (the import() method doesn't work). They're in the same folder on my desktop. I appreciate any help.

Hi. Welcome to python!

This is actually one of the strengths of python. This should work:

import test
test.a("Hello world")

Or

from test import *
a("Hello world")

Or

from test import a
a("Hello world")

You will generally have had to run test.py, not just saved it.

It's quite common practice to have something like this at the bottom of your test.py:

if __name__=="__main__":
    a("Hello world")

Why? Because if you run test.py, then the above will run also. But if you import test.py then the above will not run. So you can import all the methods without running the test code.

Hope this helps.
