Getting one value from a python tuple

Is there a way to get one value from a tuple in python using expressions?

def Tup():
return (3,"hello")

i = 5 + Tup(); ## I want to add just the three


I know I can do this:

(j,_) = Tup()
i = 5 + j


But that would add a few dozen lines to my function, doubling its length.

Answer

You can write

i = 5 + Tup()[0]

Tuples can be indexed just like lists.

The main difference between tuples and lists is that tuples are immutable - you can't set the elements of a tuple to different values, or add or remove elements like you can from a list. But other than that, in most situations, they work pretty much the same.
