Reminds me of Ruby's array literals:
a = %w( ant bat cat dog )
After a year of Ruby I still prefer Python.

David -- great point! Reminds me of the qw{ } stuff available in
perl. But much simpler.

A variation on the first tip is to make a list from a string.
For example, if I want days of the week in a list, I can do:

>>> 'monday tuesday wednesday thursday friday saturday sunday'.split()

It is much simple than having to type lot of quotes and comas.

Thanks for the comment!

Yeah, I use list comprehensions and generator expressions plenty too.
In this one case, I like map just because it is so much shorter.

I'd write the 2nd example using a list comrehension:

>>> x = [1, 2, 3]
>>> ', '.join([str(z) for z in x])
'1,2,3'

or using a generator comprehension for python 2.4 and up :

>>> x = [1, 2, 3]
>>> ', '.join(str(z) for z in x)
'1,2,3'

which is is more natural (at least for me ;)
