Re: Python internals

Hi! *I am slowly teaching myself Python. *I was reading David Beazley's
excellent book "Python - Essential Reference"; in particular about
variables. *Let me quote:

"Python is a dynamically typed language in which names can represent
values of different types during the execution of a program. In fact the
names used in the program are really just labels for various quantities
and objects. The assignment operator simply creates an association
between a name and a value. This is different from C, for example, in
which a name (variable) represents a fixed size and location in memory..."

As an old mainframe programmer, I understand the way C does things with
variable but this text got me wondering how Python handles this
"association" between variable name and value at the lower level. *Is it
like a fifo list?

If there is any Python guru that can help I would be most interested in
your thoughts.
They're stored in a dictionary (hash table), called a "dict" in
Python, the name being the key and the value being a reference to the
actual value. The CPython implementation is written in C (hence the
name) and implements references with pointers.
