You know, one or two examples was probably plenty. The other six or seven
didn't add anything to your post except length.
Also, type testing by equality is generally not a good idea. For example:
class HexInt(int):
"""Like built-in ints, but print in hex by default."""
def __str__(self):
return hex(self)
__repr__ = __str__
You should be able to use a HexInt anywhere you can use an int. But not
if your code includes something like this:
if type(value) == int:
do_something()
else:
print "Not an int!"
(What do you mean my HexInt is not an int? Of course it is.)
Better is to use isinstance(value, int). Better still is to do duck-
typing, and avoid type() and isinstance() as much as possible.
