Python - Object

1 - About

Language - Object in Python.

In Python everything is an object including:

3 - Comparison

Comparing objects of different types is legal.

The outcome is deterministic but arbitrary: the types are ordered by their name. Thus, a list is always smaller than a string, a string is always smaller than a tuple, etc. Mixed numeric types are compared according to their numeric value, so 0 equals 0.0, etc.

The rules for comparing objects of different types should not be relied upon; they may change in a future version of the language.
