No. It's not a tuple in your case (calling 'setup' function)

a = 1,2,  # <- extra comma
print a
b = 1,   # <- extra comma
print b

=>

(1, 2)  # ignored
(1,)    # made tuple

and

def f(a, b):
    print a,b

f(1,2,)   # <- extra comma

=>

1 2  # ignored

Under some circumstances python ignores "excess" comma. At least
inside list definition [1,2,3,]  and function calls f(1,2,)
