I don't' understand the question, but if you are just trying to exchange 
the values of x and y, this will do:

x,y = y,x


If you want a function to return several values to several variables, try:

def fn(...):
     # calculate a and b
     return a,b

p,q = fn(...)

All these comma-separated sequences are tuples, often written with 
parentheses as (x,y)=(y,x) and (p,q)=fn(...), but as here,  the 
parentheses are often not necessary.
