Surely not necessary. There's a generous recent thread about books on

Hello and welcome,
the answer is a definitive "it depends" ;-)
Generally you do not need knowledge in C for learning Python.
But I'd say that it will not hurt to have some knowledge. Especially
some packages use C-code to extend Python. But it seems to me that you

No, I would not say that learning C is essential for learning Python. However,
C can serve as a great set of fundamentials in programming and understanding
machines

I'm a C++ programmer and Python programmer as well. Python classes are not
exactly like C++ classes.
If you define a class where every method has an implementation, then it really
isn't abstract. It can be instantiated. You can force it to be abstract by
doing from abc import ABCMeta and dec

This is actually part of a not entirely uncommon misconception that can
arise by comparing objects only by their
repr() outputs (the string representation created when you pass them to
print).
You're comparing the ID or memory address of the objects and determining
they must be the same object. In
Thanks to all who helped. As was previously pointed out, many other languages
use truncation rather than rounding for // division.
Getting the behavior you want may be as easy as replacing // with the int()
function
>>> x = 9 ; y = 2
>>> x // y, -x // y, (-x) // y
(4, -5, -5)
>>> int(x /

I think Ian looked up the first post on Google Groups, where your code
was evident. The message was incomplete when it got here (the mailing
list); I don't know why.
Thanks. I didn’t post new code. I was just referring back to original

I’m guessing difference between Java and Python is that Java BigIntegers do
not switch to floor for negatives.
Possible to tweak rounding of Python to be li

If your post had an attachment, be aware that the python-list list drops
all attachments - it is a text only list. Please paste your code

I have no idea what you're replying to, but integer division with
negative numbers IS well defined. Python will floor - it will always
round down.

That's an edge-case alright. Fortunately, I've decided to not skip
lambdas. That's too problematic, it's easier to parse them as a
special-case. Thanks for pointing this out.

This very useful, I will look into it, thanks.

Sorry, didn't address this. This is fine too, since I'm assuming that
only methods named __init__ are allowed to mutate the object.
Because 'setup' is not '__init__' it's disqualified.
