Python Library Reference: 3.1 Truth Value Testing:
Any object can be tested for truth value, for use in an if or while
condition or as operand of the Boolean operations below. The following
values are considered false:
None
False
zero of any numeric type, for example, 0, 0L, 0.0, 0j.
any empty sequence, for example, '', (), [].
any empty mapping, for example, {}.
instances of user-defined classes, if the class defines a __nonzero__()
or __len__() method, when that method returns the integer zero or bool
value False.3.1
All other values are considered true -- so objects of many types are
always true.
