a.close()

Hi!
Can I ask a few questions? (Other than this one...)
What output did you expect? A string, tuple, or what? I'm not strong with
cgi stuff.
Also, you don't need the string module 1) because you don't use it 2)
because you can use string methods.

Hi all,
I'm having a problem that is ticking me off. (to put it lightly)
Why does decimal do this -- I thought that getcontext().prec was number of
decimal places?
import decimal
decimal.getcontext().prec = 2
a = decimal.Decimal(2)
b = decimal.Decimal(3)
100*a/b
Decimal("67")
print 100*a/b
67
Okay, so how do I get decimal to set precision of *significant digits*?
Why have a decimal.getcontext().prec if it doesn't provide a useful result?
The number of digits in a number is irrelevant to that numbers value.
It just doesn't make sense to me.
I tried quantize the other day and it didn't wo
Just one question...
Why are you off the list?
I see no point.
If you want to stop getting the mail, you can change the options of your
list account online...
That's the only reason I see...
Let's see -- reasons
1. Cost -- No, it's free
2. Security -- If you were subscribed to it once, it's too l
Filter can be replaced with IMHO the more readable list comprehensions.
I would try
def get_fles(exts,upd_dir):
"return list of all the files matching any extensions in list exts"
fle_list = []
for each in exts:
ext_ls = glob.glob("%s*.%s" % (upd_dir,each))
fle_list.extend(ex
This will get a random record
I hope you do not think the comments are patronising
but you did say you are new so I did not want to give
naked code.
import random
#the above gives the program the ability to get a
#pseudo random number
file = open('test.rantxt')
listcontents = file.readlines()
#give
Ahh, my pitiful form of flattening a list that cheats...
def flatten(li):
li = str(li)
li = li.replace("[","")
li = li.replace("]","")
li = li.replace("(","")
li = li.replace(")","")
li = "[%s]"%li
return eval(li)
It works! It's probably just a bit slower.

Hi all.
Long time no see. (About five days, right?)
Anyway, I know the first thing that some of you are going to say is using
eval(). I don't want a whole
guilt trip on security risks and all that. I do not want to share the code
with anyone else while it's on my
computer, and I sure don't hav
Thanks everyone!
Kent started the suggestion of making a code object, but everyone else seems
to have worked their way to it.
Beautiful! I only have to call exec once, and it cuts down time
considerably.
Here is the new code.

Please remind me if I've forgotten anything.
### Start #
col2_set = sets.Set(col2)
how can I get a uniq elements that repeated several
times:
for item in range(len(list)):
for k in range(len(list)):
if item == k:
if list[item] != k[list]:
print item
First off, this would never work. You are iterating over the s
Try this
def findfile(thefile,
toplevel="C:\\windows",findcount=-1,subdirectories=True,returnlist=False):
results = []
t = 0
if subdirectories:
for root,dirs,files in os.walk(toplevel):
for x in files:
fullname = os.path.join(root,x)
if x.lo
Its not so much a criterion that they *should* be used that way,
its just that its what they do. A list comprehension creates a list!
Thats why they are called *list* comprehensions. :-)
See, I'd always figured that the reason it was called a list
comprehension was because the list comprehension o
You're my best friend. Everyone else looves camelCase, and I hate it too. It
doesn't make sense. It doesn't fit English.
It doesn't fit Spanish. It doesn't fit any other language AFAIK, so why
should a human (who uses spoken language) to computer interpreter use a
naming convention that doesn't
I noticed that too, Liam.
b = input("Weather is really bad, still go out to jog? [y/n]") # Would
it kill you to have whitespace in a prompt?
should really be
b = raw_input("Weather is really bad, still go out to jog? [y/n]")
to get the effect he wants.
input() doesn't only take integers,

I got out of the habit of using them really fast.
Also, __ & _ tend to have special meaning in Python (which is bad
enough as it is), so I don't use them for that reason as well.
