list-comprehension

Hi, folks

have a look at the following piece of code, which shows a list comprehension..

>>> i = 6
>>> s = [i * i for i in range(100)]
>>> print(i)

When you execute the code example in Python 2.6 it prints 99, but when you execute it in Python 3.x it prints 6.

What were the reason for changing the behaviour and why is the output 6 in Python 3.x?

Thank you in advance!

I am beginning the process of moving code over to PHP 5.3 and one of the most highly touted features of PHP 5.3 is the ability to use closures.

Python serialize lexical closures?

Is there a way to serialize a lexical closure in Python using the standard library? pickle and marshal appear not to work with lexical closures. I don't really care about the details of binary vs. string serialization, etc., it just has to work. For example: def foo(bar, baz) : def closure(waldo)… >>> More
