Re: sparse sets of integers?

You have sets in Python 2.3x and 2.4x. I don't know if they can handle your amounts of data, but i guess so. -- http://mail.python.org/mailman/listinfo/python-list

Re: Counting iterations

You should avoid the "a" + "b" + "c" -kind of concatenation. As strings at immutable in Python you actually makes copies all the time and it's slow! The alternative used in Steven Bethard's example is preferable. -- http://mail.python.org/mailman/listinfo/python-list

Re: Python documentation moronicities (continued)

Seems like criticising the manual is som kind of heresy. So be it. You know, the Re documentation contains many pages. Ufortunately I didn't dwell with the first introductory paragraph, I was trying to solve a particular problem. I'm not that used to looking for links to external sources in the m

Re: Python documentation moronicities (continued)

Steve, thank you for givig me those links. I'll go there if I manage to structure an improvement suggestion. And about the link to the Howto: I suppose many people don't read the manual from a to z but with a particular problem in mind. Hence the link could ble locateded several places, perhaps re

Piping data into script under Win32

I trying to figure out a way to make a python script accept data output from another process under Windows XP, but I fail miserably. I have a vague memory having read this is not possible with Python under Windows... But googling for a clue I came across this from /Learning Python/ (Lutz & Ascher)

Re: Piping data into script under Win32

You being so sure about what you were saying, was what I needed. Thanks! Under Windows, I'm used to rely on the PATHEXT env. variable, so I typically don't write "python scriptname.py args", but just "scriptname args". So: type countlines.py | python countlines.py = Success type countlines.py | c

Finding name of running script

Is it a more pythonic way of finding the name of the running script than these? from os import sep from sys import argv print argv[0].split(sep)[-1] # or print locals()['__file__'].split(sep)[-1] # or print globals()['__file__'].split(sep)[-1] -- http://mail.python.org/mailman/listinfo/python-l

Re: Finding name of running script

Thanks! That's os.path.basename() I guess. It's better, but still complex. I have a _nof_ = argv[0].split(sep)[-1] in my script template and use it under the usage() function to tell what the script does, like: "cf.py counts files in directory or directory structure" If I change the filename,

Re: Behaviour of str.split

The behaviour of "".split("*") is not that strange as the splitpoint always disappear. The re.split() have a nice option to keep the splitpoint which the str.split should have, I think. One expectation I keep fighting within myself is that I expect "mystring".split('') to return ['m', 'y', 's',

Setting win32 console title from Python

Hi, I'm trying to set the title of the console window (CMD.EXE) in Windows. I want it set to the basename of the current directory and it should stay after the script has finished. Now, the console title is easily set with the DOS-command 'title NewTitle'. But I'd like to do this from a Python scr

Re: Setting win32 console title from Python

Hi Jay. It seems like my requirement is a light edition of your. I like having many console windows open, and to make it easier to switch between them, I like to name them. Todays solution is rather tedious - a batch file that calls a python script that isolates the directory name and stores it i

Re: Setting win32 console title from Python

Hi Duncan, sorry, I was unprecise. I'm thinking of a script, called t.py that can be used in the console like an ordinary command. Som if I change directory from S:\scripts to d:\projects and execute the script the title changes to "projects" etc. I have that functionality today with a combina

Re: Unique Elements in a List

Your set-approach is very nice, but if the list of data is huge, it is rather slow because you'll have to loop through the data list and count every member. -- http://mail.python.org/mailman/listinfo/python-list
