A little annoyed one day that I couldn't use the statefulness of
generators as "resumable functions", I came across Hettinger's PEP 288
(http://www.python.org/peps/pep-0288.html, still listed as open, even
though it's at least a year old and Guido doesn't seem very hot on the
idea). I'm not too sure of its ideas on raising exceptions in
generators from outside (although it looks like it might be convenient
in some cases), but being able...

Found myself needing serialised access to a shared generator from
multiple threads. Came up with the following

lock = threading.Lock()
while 1:
lock.acquire()

next = gen.next()

Hi,
When list comprehension was added to the language, I had a lot of
trouble understanding it but now that I am familiar with it, I am not
sure how I programmed in Python without it.
Now I see that generator expressions have been added to the language
with 2.4 and I question the need for it. I know that it allows for lazy
evaluation which speeds things up for larger lists but why was it
necessary to add it instead of improving list...

I've been playing around with generators and have run into a
difficulty. Suppose I've defined a Node class like so:
class Node:
def __init__(self, data=None, left=None, right=None):
self.children =
self.children.append(left)
self.children.append(right)
self.data = data

Hi,
I'm trying to figure out what is the most pythonic way to interact with
a generator.
The task I'm trying to accomplish is writing a PDF tokenizer, and I want
to implement it as a Python generator. Suppose all the ugly details of
toknizing PDF can be handled (such as embedded streams of arbitrary
binary content). There remains one problem, though: In order to get
random file access, the tokenizer should not simply spit out a series...

Ok, I know all about how binary numbers translate into text characters.
My question is what exactly IS a text character? Is it a bitmap?

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. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...
