All discussion is about python 3.1.2; see Python docs for the source of my question. I know what zip does; I just don't understand why it can be implemented like this: def zip(*iterables): # zip('ABCD', 'xy') --> Ax By iterables = map(iter, iterables) while iterables: yield tuple(map(next, iterables)) Let's say I ...

In my project I have to stick to Python 2.5 (Google App Engine). Somewhere in the application (actually a framework), I have to keep track which variables are defined and in which order they are defined, in other words I would like to intercept whenever an assignment operator is processed. Using Python 3, I would define a metaclass M wi...

Example, if I want to load an image and print the content of her first pixel, i will write in C++ : #include <opencv/cv.h> #include <opencv/highgui.h> using namespace std; int main() { IplImage *img; img = cvLoadImage("/home/foo/f...
(Using Python 3.1) I know this question has been asked many times for the general question of testing if iterator is empty; obviously, there's no neat solution to that (I guess for a reason - an iterator doesn't really know if it's empty until it's asked to return its next value). I have a specific example, however, and was hoping I ca...
(In Python 3.1) (Somewhat related to another question I asked, but this question is about iterators being exhausted.) # trying to see the ratio of the max and min element in a container c filtered = filter(lambda x : x is not None and x != 0, c) ratio = max(filtered) / min(filtered) It took me half hour to realize what the problem is ...

Hi, I am working on a script to download and process historical stock prices. When I used urllib.request.urlopen I got a strange prefix of text in every file (b'\xef\xbb\xbf) that was not present when I used urllib.request.urlretrieve, nor present when I typed the url into a browser (Firefox). So I have an answer but I don't know why i...

(In Python 3) I have dictionary old. I need to change some of its keys; the keys that need to be changed and the corresponding new keys are stored in a dictionary change. What's a good way to do it? Note that there may be an overlap between old.keys() and change.values(), which requires that I'm careful applying the change. The followi...
I am writing a small diagram drawing application (similar to Graphviz in spirit), and need a GUI library that would allow me to embed a canvas capable of drawing anti-aliased lines and text. I want to have a text editor in one half of the window to edit the diagram code and a (perhaps live) preview pane in the other. Right now I have th...
Is there any idiom for getting an arbitrary key, value pair from a dictionary without removing them? (P3K) EDIT: Sorry for the confusing wording. I used the word arbitrary in the sense that I don't care about what I'm getting. It's different from random, where I do care about what I'm getting (i.e., I need probabilities of each item ...
