Tuples: Immutable Sequences


Python provides an immutable sequence called tuple

Similar to list but:
literals listed in () Aside: singleton (3,)
only sequence operations apply (+, *, len, in, iteration)
more efficient in some cases

Tuples (and lists) are transparently "unpacked"
>>> p1 = (3,4)
>>> x1, y1 = p1
>>> x1
3
>>> y1
4
