Hi there,
I'm learning Python at the moment and trying to grok the thinking behind
it's scoping and nesting rules.
I was googling for nested functions and found this Guido quote:
(http://www.python.org/search/hypermail/python-1993/0343.html)
"This is because nested function definitions don't have access to the
local variables of the surrounding block -- only to the globals of the

I am relatively new to python, but i know some other languages, such as C++,
fairly well.
After reading up a little bit in the reference manual, section 4.1,
and searching this NG, i still have 2 questions about python's scoping
rules.
1. Exactly what are the major differences between python's and C++ scoping
rules?
2. Why is it that 'while', 'for', etc., don't introduce a new block?

Here's a sentence from Learning Python:
"Names not assigned a value in the function definition are assumed to be
enclosing scope locals (in an enclosing def), globals (in the enclosing
module's namespace) or built-in (in the predefined __builtin__ names
module Python provides."
I have trouble reading this sentence. First, I don't understand if the
word 'enclosing' is a verb or an adjective. The whole flow of the
sentence seems...

Hello all,
The following is a copy of a blog entry. It's asking a question about
future statements and the built in compile function. I'd appreciate any
pointers or comments about possible approaches.
`Movable Python <http://www.voidspace.org.uk/python/movpy/>`_ supports
running both Python scripts and ``.pyc`` bytecode files. It does this
by compiling scripts to bytecode, or extracting the code object from
bytecode files, and then...

Hi,
I am trying to work out why I get UnboundLocalError when accessing an
int from a function where the int is at the global scope, without
explicitly declaring it as global but not when accessing a list in
similar circumstances.
The documentation: http://docs.python.org/ref/naming.html does not give
me enough info to determine why the difference exists as it does not
seem to mention types at all..

anyone advise please?

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention.

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
