For example
def sum(a,b):
return a+b
def main():
x = sum(9,7)
print(sum)
or you can use
def sum(a,b):
print(a+b)
def main():
sum(9,7)
either way, you will get the same result. It's really up to you. what you prefer?

isn't a function, it's a keyword. It lets functions have a return value. You can use the value returned from a function somewhere else by assigning it to a variable, or by using it as an argument to another function.
def giveMeANumber():
return 42
num = giveMeANumber()
sum = addNumbers(num, 5)
sum2 = addNumbers(giveMeANumber(), giveMeANumber())
print
is a function. It doesn't return anything, but it has a side effect of sending output to the console.
print("hello world") # you'll see "hello world" in the console
hello_world = print("hello world") # this doesn't work....
