Call a variable outside of a function?

Question

For example:

def test(a)
   a = 2
   b = 5+a
   x = a*2
   return x

Is there a way to call the variable 'b' outside of the function?

Answer 1

b = None

    def test(a)
       global b
       a = 2
       b = 5+a
       x = a*2
       return x

print(b)

Although we will suggest to return b and then access it, as global variable is a bad idea. See this, Why are global variables evil?
