It's a fundamental term from object-oriented programming.
If you have a class that defines certain data and behaviour, you can
create a *subclass* that inherits the same data and behaviour, except
for specific examples which are over-ridden or over-loaded.
A simple example:
class MyInt(int): # creates a subclass of int
def __str__(self):
return "My Integer %d" % self
MyInts are exactly the same as built-in ints except their string form is
different.
>>> n = MyInt(42)
>>> print n
My Integer 42
