Given [1,2,3,4,5], how can i do something like 1/1, 1/2, 1/3,1/4,1/5, ...., 3/1,3/2,3/3,3/4,3/5,.... 5/1,5/2,5/3,5/4,5/5 I would like to store all the results, find the minimum, and return the two numbers used to find the minimum. So in the case i've described above i would like to return (1,5). So basically I would like to do somethin...
The question is in the title. I'd like to do in Python what I do in this example in C: #include <stdio.h> int main() { int i; for (i=0; i<10; i++) printf("."); return 0; } Output: .......... In Python: >>> for i in xrange(0,10): print '.' . . . . . . . . . . >>> for i in xrange(0,10): print '.', . . . . . . . . . . ...

How to print the following code to a .txt file y = '10.1.1.' # /24 network, for x in range(255): x += 1 print y + str(x) # not happy that it's in string, but how to print it into a.txt There's copy paste, but would rather try something more interesting. ...
This has always confused me. It seems like this would be nicer: my_list = ["Hello", "world"] print my_list.join("-") # Produce: "Hello-world" Than this: my_list = ["Hello", "world"] print "-".join(my_list) # Produce: "Hello-world" Is there a specific reason it does it like this? ...
I have a sequence of x, y and z -coordinates, which I need to manipulate. They are in one list of three tuples, like {(x1, y1, z1), (x2, y2, z2), ...}. I need addition, multiplication and logarithm to manipulate my data. I would like to study a module, which is as powerful as Awk -language. ...
My primary language right now is D, and I'm in the process of learning Python because it's required for a course I'm taking. While I understand why dynamic languages would be a breath of fresh air for people programming in static languages without type inference or templates (IMHO templates are to a large extent compile-time duck typing...

Background: I working on an application on Google App Engine. Its been going really well until I hit one of their limitations in file size -- 1MB.

I am writing a Python utility that needs to parse a large, regularly-updated CSV file I don't control. The utility must run on a server with only Python 2.4 available. The CSV file does not quote field values at all, but the Python 2.4 version of the csv library does not seem to give me any way to turn off quoting, it just allows me to...

Updated: EDIT! I have coded the program wrongly. Instead of returning the Fibonacci numbers between a range (ie. startNumber 1, endNumber 20 should = only those numbers between 1 & 20), I have written for the program to display all Fibonacci numbers between a range (ie. startNumber 1, endNumber 20 displays = First 20 Fibonacci numbers). ...
I'd like to register a protocol handler, like "myapp:", across OS X, Linux, and Windows, so that when someone clicks a url like "myapp://some/params" in a web browser, a python script will be called and passed in those params. Obviously this would require something being installed on each machine to enable it, but just trying to figure ...

Surely there is a better way to do this? results = [] if not queryset is None: for obj in queryset: results.append((getattr(obj,field.attname),obj.pk)) The problem is that sometimes queryset is None which causes an exception when I try to iterate over it. In this case, I just want result to be set to an empty list. This co...
Hi, I'm new to python, so please excuse what is probably a pretty dumb question. Basically, I have a single global variable, called _debug, which is used to determine whether or not the script should output debugging information. My problem is, I can't set it in a different python script than the one that uses it. I have two scripts:...
