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.
