Carrying values over in a function

[aLiase]

I'm pretty new to python, and I'm currently having problems carrying a value inside a function, to be used again by another function.

I'm not sure if that make sense, and I don't really have a good simple example, sorry.

And since I'm totally new to programming I might just be misunderstanding what a function really does.

I hope this helps with some basic understanding of the way functions work:

# functions receive values in the parameters given in the fuction call
# and return values that they produce using the return statement
 
def Add(x, y):
    return x + y
 
def Multiply(a, b):
    c = a * b
    return c
 
d = Add(1, 2)
print d
 
e = Multiply(d, 6)
print e

Yes, that really helped thanks, program works fine now : D.

I didn't actually know you could assign a variable to a function.

I remember programming in Pascal. Back then we were force to make a distinction between functions and procedures. For Python this is not so. But there some little pieces of trivia that is good to know...

1. When a function (or method of an object) does not explicitly return a value, Python automatically returns None.
2. Even if a function returns a value you are not require to assign it to a variable.
