Sure; get familiar with a swiss-knife module, itertools, and in
particular for this task, groupby:
from operator import itemgetter
from itertools import groupby, chain
def group_roster(rows, num_stats=12):
# group the rows by their first two elements
# Caveat: the rows should already be sorted by
# the same key
for key,group in groupby(rows, itemgetter(0,1)):
stats = [0.0] * num_stats
for row in group:
if row[2]: stats[int(row[2])-1] = float(row[3])
yield list(chain(key,stats))
if __name__ == '__main__':
import csv
for row in group_roster(csv.reader(open('roster.txt'))):
print row

This stores the values as a list of lists, each list corresponding to a

If you insist on using exec (which, again, you have no reason to for
this example), take the union of d's globals and locals as f's
globals, and store f in d's locals():
from math import *
G = 1

g.update(locals())

csvutils is a single Python module for easily transforming csv (or csv-
like) generated rows. The release is available at
http://pypi.python.org/pypi/csvutils/0.1.

What is csvutils?
The standard csv module is very useful for parsing tabular data in CSV
en't so many or compelling use cases for rationals as
for decimals (mainly money counting).

from itertools import islice, chain, repeat
def unpack(iterable, n, default=None):
return islice(chain(iterable,repeat(default)), n)

andard exception classes were old-style so it's not safe to
assume that you only have new style classes to worry about when the
very standard library includes lots of legacy code.

Even if it's technically possible and the change doesn't break other
things, I'd rather not have to maintain a patched version of the
stdlib.

Here's the relevant thread: http://preview.tinyurl.com/2aeswn. Note
that the builtin eval() is around 5x faster than this parser, and from
the statement above, 50x faster than the pyparsing solution.

:-) Are you a fiction writer by any chance ? Nice story but I somehow
doubt that the number of lines of the form "name = 0x" ever written in
Python is greater than a single digit (with zero the most likely one).

e alternative implementations. E.g., multiple
processors in parallel, more efficient algorithms, ctypes or pyrex to
speed up the python.
In terms of the overall project notion-to-delivery duration,
implementing in Python might be the right first step on your way to an
assembler implementation.
sssibly do the whole job, could it?"
If you have a good regression test suite, you are done when it works.

You can even shadow the builtin len() if you prefer:
import __builtin__
def len(iterable):
try: return __builtin__.len(iterable)
except:
i = 0
for x in iterable: i += 1
return i

I guess you want something like:
while True:
random.shuffle(letters)
trans_letters = ''.join(letters)[:len(original_set)]
if some_compatison(original_set,trans_letters):
trans_table = string.maketrans(original_set, trans_letters)
for report generation ?

How is this worse than list(itertools.count()) ?
