Is there a way of returning a value that can be used in the rest of the code?

How can I use a returned value in python? Here is what I mean

import random

def rand(n1,n2):
    a = random.randint(n1,n2)
    print(a)
    return a

rand(1,6)

def do_something(a):
     b = (a**2)
     print (b)
     return b

print (do_something())

I want to take the random number that is returned from rand() and use it in another function, but I can't seem to get it to work. Where am I going wrong? I know that inside the DEF, it is a local variable and that is why it is not recognized - is there a way around this? So when a value is returned, it is considered a global variable?

Set it to global, I figured it out.
