It is left over from the example I stold it from, I remove it and see if that helps.

Yet (I believe that) a complete IDE can bring functions that an editor, however powerful, cannot (I still use emacs). I have tried Komodo, Wing, Eric3, Idle, emacs, (not vi ;-) ), SPE, boa-constructor, .... and many more - I like most of them but am really addicted to eclipse + pydev. ... but even without pydev, I would not use java just because of eclipse. hg

As you have noticed, you must provide security assertions for your objects so it's not an easy way.

Possible to assure no "cyclic"/"uncollectible" memory leaks?
by Joe Peterson Dec. 2, 2006

Dec. 2, 2006

I've been doing a lot of searching on the topic of one of Python's more disturbing issues (at least to me): the fact that if a __del__ finalizer is defined and a cyclic (circular) reference is made, the garbage collector cannot clean it up. First of all, it seems that it's best to avoid using __del__. So far, I have never used it in my Python programming. So I am safe there. Or am I? Also, to my knowledge, I have never created a cyclic reference, but we do not typically create bugs intentionally either (and there are certainly times when it is an OK thing to do). Still, it's not comforting to know that it is possible to create a situation that would create a memory leak using a language that is supposed to relieve us of that worry. I understand the problem, but it would be nice to know that as a programmer, I could be assured that Python would always deal with memory management and that memory leaks were not something I had to think about. So here's a question: if I write Python software and never use __del__, can I guarantee that there is no way to create a memory leak? What about system libraries - do any of them use __del__, and if so, are they written in such a way that it is not possible to create a cyclic reference? Thanks, Joe

strange problems with code generation

I am writing out zero byte files with this (using python 2.5). I have no idea why I am having that problem, I am also looking for an example of readlines where I can choose a number of lines say lines 12 to 14 and then write them back to disk. any help would be apreaceted. import sys as sys2 import os as os2 def playscoreinrange(from_file, fromline, toline): "untested way to play a series of lines from a orc, sco combination line 14 may not be correct" print(from_file) fromfile = os2.path.basename(from_file) print(fromfile) orcfilename = fromfile[:-4] + '.orc' print(orcfilename) infile2 = open(orcfilename, 'r') outfile2 = open('temp.orc', 'w') for line in infile2: outfile2.write(line) infile = open(fromfile, 'r') outfile = open('temp.sco','w') data = sys2.stdin.readlines() print(data) for linenumber in range(fromline, toline): outfile.writeline(data[linenumber]) https://sourceforge.net/projects/dex-tracker http://www.dexrow.com os2.startfile('temp.bat')
