Question

1. What is the definition of tuple equivalence in python?
2. If two tuples have the same element regardless of order, are they equivalent tuples?

I looked in python documentation on tuples equivalence, however, it was not very clear description.
http://docs.python.org/2/tutorial/datastructures.html

Answer 1

Such things are defined in the language reference, not in the tutorial.

Tuples and lists are compared lexicographically using comparison of
corresponding elements. This means that to compare equal, each element
must compare equal and the two sequences must be of the same type and
have the same length.
