How to call function which is in one program ...

[Shahriar Shamil Uulu]

Dear All,
i got another questions. For example i have two programs in python
like: first.py, second.py.
In first.py i have a function test() like:
# first.py
...
def test(name):
      print name

.... so other functions
=========================

#second.py

Question is how i can include first.py into second.py and use function
test.py.
Thank you ...
