How to call a function defined in another py file

[silverburgh.meryl]

Hi,

I have a function called 'test' defined in A.py.
How can I call that function test in my another file B.py?

Thank you.

In B.py:

import A

A.test()

In B.py:

import A

A.test()

But Do I need to put A.py and B.py in the same directory?
if not, where does python look for A.py ?
And do I need to compile A.py before I can import it to B.py?

No, but then you have to take certain precautions. (*)

if not, where does python look for A.py ?

In the path defined by the (IIRC) PYTHONPATH (*)

And do I need to compile A.py before I can import it to B.py?

No.

(*) you might want to read the fine documentation at
http://docs.python.org/tut/node8.html
which tells it much better than I do, and might give you
some more ideas for googling.
I haven't had yet the necessity for cross-directory imports.

No, they do not have to be in the same directory. A.py needs to be in
your path.

And do I need to compile A.py before I can import it to B.py?

No
