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.
