Question

I am currently trying to learn how to use define functions using python and I am confused on what "return" does in code.

for example in lecture there were two different examples:

example 1)

def fun(a):

return a+2

x=fun(2)*fun(3)

what is the value of x?

a) 9

b) 4

c) 16

d) none of the above

example 2)

def fun(a,b):

c=((a+” “)*len(b)).title()

return c

x=fun(“ab”,”caa”)

What is the value of x?

Can you please explain what the return does and how the answer in number two differs from one which would be

def fun(a,b):

c=((a+” “)*len(b)).title()

x=fun(“ab”,”caa”)

thanks!
