[Tutor] Upgrade to 2.4
I compiled Python 2.3.4 from source, but now I would like to upgrade to 2.4. There doesn't seem to be a "make uninstall" target for 2.3.4. Will compiling 2.4 overwrite the older version, or will I have two versions of Python on my system? Thanks, Will ___ Tutor maillist - [EMAIL PROTECTED] http://mail.python.org/mailman/listinfo/tutor

Hi Will, According to the README, you can install Python 2.4 in a way that doesn't overwrite your older version of Python. Here's a snippet from the README: """ If you have a previous installation of Python that you don't want to replace yet, use make altinstall This installs the same set of files as "make install" except it doesn't create the hard link to "python" named "python" and it doesn't install the manual page at all. """ This should install '/usr/local/bin/python2.4', but otherwise, it should leave the rest of your Python 2.3.4 installation intact. Hope this helps! Yeah, I saw that, but didn't want two versions of Python hanging around. I went ahead and did "make install" for 2.4 and it replaced the previous version.

[Tutor] Scrabble Help
I'd like to write a program to help find words for Scrabble but I've been having trouble right from the beginning. tiles = 'aeirstw' dictionary = ['aardvark', 'cat', 'dog', 'taste', 'stare', 'wrist'] for word in range(len(dictionary)): for letter in range(len(dictionary[word])): if dictionary[word][letter] in tiles: nothing here quite works I guess what I'm trying to do is step through every letter of every word in my dictionary and if that letter is in my tiles set it aside and compare it back to the dictionary. So in the dictionary above, 'aardvark' would not be included because there is only 1 'a' in my tiles, but 'stare' and 'wrist' should be even though there are letters left over in the tiles. Am I going about this wrong? Should I be looking at some module or a regular expression? Of course any advice is appreciated.

[Tutor] <> and chomp
Hi, I'm new to programming and started with Perl but have been reading a lot of good things about Python. Thought I would switch before I have too much time invested in Perl. Anyway, my question is, is there something in Python similar to the diamond operator and chomp from Perl? I'm trying to read in from a file line by line and get rid of the '\n' at the end of each line. Thanks, Will ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
[Tutor] Better way to substitute text?
Hi,
Just learning Python, on chapter 6 of Learning Python 2nd Ed. So, on to
the question. Is there a better way to
implement the code below? It scans a saved html file and highlights
certain keywords is a bold, red font. It works,
but I suppose I'm wondering if it's the "Pythonic" way.
Thanks,
Will
#!/usr/bin/env python
in_put = open('test.html', 'r')
out_put = open('test_highlight.html', 'a')
for line in in_put:
line = line.replace("TWY", "TWY")
line = line.replace("RWY", "RWY")
line = line.replace("WIP", "WIP")
out_put.write(line)
in_put.close()
out_put.close()

Thanks Shantanoo,
I like that a lot better. Had to modify it just a little.
replace_words = ['TWY', 'RWY', 'WIP']
for line in in_put:
for replace_word in replace_words:
line = line.replace(replace_word, "" + replace_word + "")
out_put.write(line)
I can never quite get when to use a nested loop.
Thanks again,
Will

Re: [Tutor] Better way to substitute text?
Thanks David,
I like that better than my original. I'll remember to NOT split the
input file into lines
in the future.

But sounds like you might want to check out easy_install, it lets you install, upgrade, and uninstall Python packages. You can even have a "custom installation location" such as in your home directory. http://peak.telecommunity.com/DevCenter/EasyInstall As far as which version to use, I think I read somewhere that the latest version of Python is typically the best version of Python.
