[Tutor] Opening Multiple Files

Hi everyone, Thanks for all suggestions. Let me just preface this by saying that I’m new to both python and programming. I started learning 3 months ago with online tutorials and reading the questions you guys post. So, thank you all very, very much…and I apologize if I’m doing something reall

Re: [Tutor] Simple way to compare Two lists

Jim & Jaggo - Dict lookup is (essentially) constant-time because the hashing function computes which unique bucket a given entry will correspond to. (Hashing functions are usually polynomials involving prime numbers. Can assume that the computation of the hash value is constant-time) So there is

Re: [Tutor] Efficiency of Doxygen on Python vs C++?

Yes but it's still a canonical question about analysis of weakly-typed dynamic languages, since my Java friend makes separate comments about scalability when analyzing large builds - he claims 1-5m lines of code is a threshold. >From: Kent Johnson <[EMAIL PROTECTED]> >To: Kevin Cameron <[EMAIL P

Re: [Tutor] Simple way to compare Two lists

Why is a dict lookup constant time. I.e. if there's a loop that walks a (shorter) list and compares each element with each element of a dict, what's going on to make this faster than an outer loop walking a list and an inner loop walking a second list? On Aug 16, 2007, at 5:01 PM, Stephen McIne

Re: [Tutor] Simple way to compare Two lists

Sorting both lists is unnecessary and not very scalable (order(NlogN)). Assuming the lists do not contain duplicates, just turn the longer one into a dict and check that each element of the shorter list in that dict (e.g. "if j not in BigList: return false") Since dict lookup is constant-time O(

Re: [Tutor] Efficiency of Doxygen on Python vs C++?

My friend clarifies: "It's not the efficiency of doxygen that's the question. The problem is that you can add fields to objects as you go in Python so you need to do a deep analysis of the code to determine the class structure which you don't have to do with C++ (or Java)." He mentioned numbers

[Tutor] Efficiency of Doxygen on Python vs C++?

My friend said the runtime efficiency of Doxygen on his build was much worse on the Python code than the C++ code, i.e. it took ages to parse the Python code. Anyone agree/disagree, or have any efficiency tips on how to structure things for decent Doxygen performance? (I haven't used Doxygen myse

Hey Everyone- I posted this to the python list, but then thought the tutor list might be a better place to get ideas. So It's hard to believe, but the planning for PyCon 2008 is underway. PyCon, an annual gathering of Python enthusiasts -- nearly 600 in Dallas last year -- will be held in C

I wasn't familiar with it prior to this thread, as previously I'd had the good fortune to use normalized data. I guess more pristine data environments spoiled me into writing less robust code. So although I asked what turned out to be the wrong question, I seem to be getting a consensus answer I'm

dear fellow Python enthusiasts, I recently wrote a script that grabs a file containing a list of ISO defined countries and creates an html select element. That's all well and good, and everything seems to work fine, except for one little nagging problem: http://en.wikipedia.org/wiki/Aland_Island
