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__':

colloquial (slang) use. Since the 1980's, an entry in the dictionary

Of course, as long as you write DBI2 compliant code, your app doesn't
much care which DBMS you use. The postgresql payoff is in admin
functionality and scaling and full ACID.

And to make it even more accurate, "Perl is undertaking Python in
India", since that's where the difference in favor of Python comes
from.

By the way, it's bad design to couple two distinct tasks: flattening a
(possibly nested) iterable and applying a function to its elements.
Once you have a flatten() function, deeply_mapped is reduced down to
itertools.imap.

If all you need is sequential access, you can use the next() method of
the file object:
nextline = open(textfile).next
print 'First line is: %r' % nextline()
print 'Second line is: %r' % nextline()
...
For random access, the easiest
or n in iter(lambda:random.randrange(10), 0):
print n
More generally, iter(callable, sentinel) is just a convenience
function for the following generator:
def iter(callable, sentinel):
while True:
c = callable()
if c == sentinel: break
yield c

Or if you'd rather write it in one line:
f(*(g() + (10,)))

Here's a small improvement of getgroups1, both in time and memory:
from itertools import islice
def getgroups4(seq):
idxs = [i for i,v in enumerate(seq) if v&0x80]
idxs.append(None)
return [seq[i:j] for i,j in izip(idxs, islice(idxs,1,None))]

It's not really hard to come up with a quick and dirty solution;
however if this isn't a homework or a toy program, take a look at the
interval module (http://cheeseshop.python.org/pypi/interval/1.0.0) for
a more thought-out design.

I suspect the trailing comma is the issue. Googling for "xlc enumerator
trailing comma" gave me
http://sources.redhat.com/ml/gdb/1999-q1/msg00136.html
which says "AIX 4.2.0.0 xlc gives an error for trailing commas in enum
declarations".
