or you can also run your module with -i (interactive) argument, which 
means to put you into the interactive mode after the module ends.

# mycode.py
def foo(): 
    print 'bar'
print 'output of program (if any)'

# then run this in your shell:
$ python -i mycode.py
output of program (if any)
>>> foo()
bar
