[Tutor] List of lists optimization and printing.
Hello. Yes, catb.org and so on. I was searching for some kind of finding max width in a table (a list of two lists) and had found this mailing list. So I want somebody to look at my code and say what can be done better from a programmer point of view. Just SQL like printing and writing. I mean optimization. I always want to know what is the best way. Thanks. * I don't know is it good to paste 62 lines there so here's the pastie http://pastie.org/2291721 I hope it will be monospaced.^U I know about SQLAlchemy but I just want to have my data in plain text because I can't find good cross-platform suites to keep contacts, many contacts. I mean phone number, name and so on. Something for a little bit entertprise tasks. Yes. Thanks. Debian bleeding edge. Python 2.6 default. And 2.7, 3.2 too.

Re: [Tutor] How to replace the '\'s in a path with '/'s?
Maybe something useful could be find in urllib? It can open local files. And UNIX slashes are equal to Web slashes. http://docs.python.org/release/3.2.1/library/urllib.request.html#urllib.request.URLopener -- class urllib.request.URLopener(proxies=None, **x509) Base class for opening and reading URLs. Unless you need to support opening objects using schemes other than http:, ftp:, or file:, you probably want to use FancyURLopener. -- >On Sat, 30 Jul 2011 22:28:11 -0700 "Richard D.

Gotcha!
http://pymon.googlecode.com/svn/tags/pymon-0.2/Internet/rsync.py
231-239 strings
## code ##
def convertPath(path):
# Convert windows, mac path to unix version.
separator = os.path.normpath("/")
if separator != "/":
path = re.sub(re.escape(separator), "/", path)
# Help file, folder pattern to express that it should match the all
file or
folder name.
path = "/" + path
return path
## code ##

Haha. Works!
Happy help you.
Ask gurus about regexps. I know they have an opinion about its speed and
optimization. So they can try to criticise. But the problem is solved. It's
good.

Nice!
That's what I've been expecting.
Thanks.
Your one string command is tiny and complete. And elegant.
Final desicion?
Or it could be something better and more professional?
So we have removed regexps and everything is fine now. Yes?
