Why can a list be compared with an integer in Python

Question

I have searched and no one seems to have this specific question. Why does Python let me compare a list with an integer? For instance,

[] < 10

evaluates to False

and

[] > 10

evaluates to True

Aren't these operations ill-defined and shouldn't Python throw an exception for these operations?

Answer 1

As of Python 3.x, you are correct this is no longer allowed

>>> [] < 10
Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    [] < 10
TypeError: unorderable types: list() < int()
