Answer 2

Python is strongly typed; such a table is not required except between basic numeric types and basic string types. For numeric types, they are coerced to long (in 2.x) or float as required. For string types, things are not as simple and so unicode (in 2.x) should be used where possible.

>>> 3 > 2.4
True
>>> 'a' < u'あ'
True
>>> u'a' < 'あ'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe3 in position 0: ordinal not in range(128)

Comparison across incompatible types in 2.x will not act as you expect.

>>> 2 < '3'
True
>>> 3 < '2'
True

Comparison across incompatible types in 3.x will fail.

3>> 2 < '3'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unorderable types: int() < str()
