How does tuple comparison work in Python?

Question

I have been reading the Core Python programming book, and the author shows an example like:

(4, 5) < (3, 5) # Equals false

So,

Answer 1

The python 2.5 documentation explains it well.

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.

If not equal, the sequences are ordered the same as their first differing elements. For example, cmp([1,2,x], [1,2,y]) returns the same as cmp(x,y). If the corresponding element does not exist, the shorter sequence is ordered first (for example, [1,2] < [1,2,3]).

Unfortunately that page seems to have disappeared in the documentation for more recent versions.
