You are apparently asking 3 questions. 

To exchange 2 values, use the tuple-unpack approach.

a, b = b, a

To get the equivalent of multiple return values,  return a tuple.

def myfunc (a):
     x = a*a
     y = 2+a
     return x, y

p , q = myfunc (5)

To avoid executing your print twice, call the function only once.

And a bonus one: to avoid my getting a blank message in this text 
newsgroup,  post in text,  not html.
