Re: [Tutor] Automatic generation of an "all possible combinations" array

Ah, in the case of looking for all n-digit bit-strings that contain exactly m-1's, the recursive solution is even nicer. Here's how I think of it: Base Case(s): - if you want 0 1's (m==0) then return all 0's. - if you want all 1's (n==m) then return all 1's. Otherwise Recursive Case: - return th

Re: [Tutor] Subclassing vs. stand alone functions

I am new to Python and trying to get my head around the OO stuff. I guess my question is - when do you go with subclassing vs. making a standalone function? OK, I'll take a slightly different approach than the other answers so far. First: procedural and OO styles of programming are diffrent

Re: [Tutor] Automatic generation of an "all possible combinations" array

The code works great, Thanks for the speedy response. The only problem which I can see is that the code scales very bad with the size of n. So, as I want a small subsection of the data (i.e lines where there are only 4 1s, number in the code below) for a system where n is large(>20). The idea is

Re: [Tutor] Subclassing vs. stand alone functions

Hi, Basically you write a (sub)class when you want to preserve state information of your instance. If the functionality in question lives longer then the scope of the function, and will be called from different methods to obtain the same information and state of the functionality at that time, it

[Tutor] Subclassing vs. stand alone functions

Hi there, I am new to Python and trying to get my head around the OO stuff. I guess my question is - when do you go with subclassing vs. making a standalone function? Let's say you want to load a dictionary. Do I create a function that accepts some argument (say a file name) and returns a dict
