Hi Lin Jin,

I am not sure I understand your question. But this silly example might
be helpful:

def get_the_number_2():
    return 2
def get_the_number_3():
    return 3
def multiply_two_numbers(x, y):
    return x * y
print multiply_two_numbers(get_the_number_2(), get_the_number_3())
>>>
6

So, one way is to use a call to one function in the argument place of
another.

You could also do:

first_arg = get_the_number_2()
second_arg = get_the_number_3()
multiply_two_numbers(first_arg, second_arg)

Are these techniques the sort of thing you were wanting?

One other thing: it is much easier to read a post if a space follows
each period. Like that. :-)

Best,
