How do you "include" a file?

How do you basically include (or import) a file?
Such that if I had:

a.py:

Code:

print 'hello'

b.py:

Code:

print 'bye'

c.py:

Code:

<import a.py>

print "---"

<import b.py>

How do I make it so that if I run c.py, it will print out:

Code:

hello

---

bye

a.py:

Code:

def dummy1():

    print "Hello"

b.py:

Code:

def dummy2():

    print "world"

c.py:

Code:

if __name__ == '__main__':

   from a import dummy1

   from b import dummy2

   dummy1()

   print '----'

   dummy2()

running python c.py will do what you want.

http://docs.python.org/release/2.6.6...l/modules.html

usualy you need to be sure that import didn't fail and use exception but probably this will be later when you will feel confortable enought with python.

Edit: two things:
- change url to point to your python version instead of 2.6.6
- i assume you don't ask about something like call, eval, exec( see the docs for details)

So there's no way to import files and have the imported file automatically evaluate its contents? In other words, if I want to import files I must ONLY have functions/classes in the file(s) to be imported? Can variables also be in it as well?

Edit: Also, how would you go about importing files from other directories? Suppose you have the following files:
include/libs.py
conf/main.py
test.py

Lets say you run test.py - how would you import the libs.py and main.py?

no, python doesn't encourage spagetti code like php, because doesn't make sense, :)
why do you want to do something like this?
