First of all, don't reply to an e-mail unrelated to your own problem,
create a new thread. The subject line is very confusing, and it also
screws up thread-based mail readers like gmail.

Not really sure, but in the future please create a new e-mail to

I was trying to build python, and this printed to the terminal:
Python build finished, but the necessary bits to build these modules were not
found:

You should use "if arg

Hello! I'm a high school student, and I'm having some trouble

For example:
Trace the sequence of recursive calls that glee(2,1) spawns:

This problem told me to use map and filter, so how would I use that to
solve it?
remove ( 5 , 6 )

remove ( 5 , 5 )
remove ( 1 , [1 , [1 , [2 , 13]] , 1 , [2] , 5] )
[[[2 , 13]] , [2] , 5]

[1 , [1 , [13]] , 1 , [] , 5]
Thanks!

That's not hard to fix:
>>> fieldnames = "abca"
>>> cols = [data[fn] for fn in fieldnames]

Hi all,
A couple days ago I posted a request for help with a strange problem
with my Battleship game. I finally double-checked the constructor for
a wx.GridSizer and, to my surprise, found that I had reversed the
column/row args in my call to said constructor. I will have to confirm
with a sighted
Oh, except one problem: the csv.DictWriter lets you tell it what order
you want the columns output in. With your version, they just show up
in whatever order Python wants them.

Aha, now this is the clever solution that I didn't find "outside the

In Python 2.7 and 3.1 [1] we now have the OrderedDict which does
preserve input order.
