actually, the C-version of strptime() is also getting called:
57765
It looks like there are two implementation of strptime() (why?) and
the one that's used by default is the Python version in _strptime.py
Unfortunately, it's pretty slow and takes up a big chunk of my code's
execution time. Is there a way to use the C version instead (is there
a C version in time.s
Hi folks,
Thanks, for all the help. I tried running the various options, and
here is what I found:
from array import array
from time import time
def f1(recs, cols):
for r in recs:
for i,v in enumerate(r):
cols[i].append(v)
def f2(recs, cols):
for r in recs:
Given a bunch of arrays, if I want to create tuples, there is
zip(arrays). What if I want to do the opposite: break a tuple up and
append the values to given arrays:
map(append, arrays, tupl)
except there is no unbound append() (List.append() does not exist,
right?).
Without append(), I am forc

First, let me admit that the test is pretty dumb (someone else
suggested it :) but since I am new to Python, I am using it to learn
how to write efficient code.
my $sum = 0;
foreach (1..10) {
my $str = chr(rand(128)) x 1024;
foreach (1..100) {
my $substr = substr($str, rand(900

Hi, I am pretty new to Python and trying to use it for a relatively
simple problem of loading a 5 million line text file and converting it
into a few binary files. The text file has a fixed format (like a
punchcard). The columns contain integer, real, and date values. The
output files are the same
