I get a list of repeated numbers [24, 24, 24, 16, 16, 15, 15 ]
Is possible get it without repeated numbers, without using set()?
If I use set, then the list is unsorted and i cann't sorting it.
For get the values i use:
[x[0] for x in cardTmp]
or:
from itertools import imap
for i in imap(lamb

Hello,
The documentation says that the built-in join method now replaces the
string.joinfield function. However how do you achieve the same
operation? The join method accepts only one argument, that is, the
list of strings to join. How do you then specify the separating
character?
Thanks
Bernar
Oh. Thanks a lot for that, now that you told me, the doc about join
makes lot more sense!
Thanks
Bernard

Suppose you want to join a list of words with hyphens.
>>> a_list = ['this', 'is', 'a', 'list', 'of', 'words']

Converting it to a set will eliminate dupes, and con

I've done:
undup = []
for i in list:
if i not in undup:
undup.append(i)
Which is simple an not very pythonic, but does the trick.

The classic way to do this kind of thing is with a dictionary:

Hi Scott,
The site ( http://www.greenteapress.com ) has a wonderful tutorial on it
for Python that quickly teaches one (within a few minutes) how to work
with dictionaries. I would highly recommend that you check it out.
It's well worth it...

Here's a function that can do what you're wanting to accomplish:

I have imported a text file consisting of lines of csv. Each line
consists of six items separated by commas. I have converted this file

the individual strings, convert five them to floats, and save them in
individual vectors

If you know they are always a contiguous string themn a simple split()
call will do it:

does not add a name to a list. Rather it creates a tuple of the new
name and the list and then binds the tuple to the list name. That's why
you wind up with the lisp style list.
To add a name to the head of the list use
listofnames.insert(0, na
