I get asked this from time to time, so for the fun of it, I’ll post this:
Tuples are immutable lists in python (and other languages). Very lightweight, unchangable arrays. They are used for storing multiple values in one variable (usually a fixed number of values).
x = (1, 2, 3, ‘abc’)
x[0]
-> 1
x[1]
-> 2
x[2]
-> 3
x[3]
-> abc
x["bob"]
-> [...]
