Broken quoting - yuck! Your newsreader is broken. Please repair it (using
third party software) or make Usenet a better place by throwing away that

It is.

If we want to keep the terminology right, Python doesn't have variables. It
has names and values. Values are bound to names. In your case:

For example:

> def foo(x):
>     print x

... you create a function object using the def statement and bind it to the
name 'foo'.

> bar = foo

Here you bind the name 'bar' to the value the name 'foo' refers to.
