Take a look at the execfile builtin.

Alternatively:

Py> exec """
... def main():
...     hello1()
...     hello2()
...
... def hello1():
...     print 'hello1'
...
... def hello2():
...     print 'hello2'
... """
Py> main()
hello1
hello2

'exec' is quite happy to deal with newlines and indenting.

Cheers,
Nick.
