Modules are namespaces. So are packages.
Classes and class instances are namespaces.
Even function scopes are namespaces. When you write:
n = None
def spam(n):
print "spam" * n
def ham(n):
print "ham" * n
the n inside spam() and ham() and the global n are in different
namespaces, and so independent.
