Try this:
------
def a():
print "this is a"
def b():
print "this is b"
lst = [a(), b()]
------
To create the list, the terms inside the list have to be evaluated.
That causes a and b to execute, and the function calls are replaced by
the each function's return value. Since your functions don't have a
return statement, the value None is returned. To see that, add this
line:
print lst
