It is XML. I used minidom from xml.dom, and it worked fine, except it
was ~16 times slower. I'm parsing a ~70mb file, and the difference is
3 minutes to 10 seconds with re's.

Hello Tutors!
I was trying to make some groups optional in a regular expression, but
I couldn't do it.
For example, I have the string:
>>> data = "42 sdlfks d f60 sdf sdf
>>> Title"
and the pattern:
>>> pattern = "(.*?).*?(.*?).*?(.*?)"
This works when all the groups are present.
>>> re.sea
Hi,
You can do the substitution in many ways.
You can first search for bare account numbers and substitute them with
urls. Then substitute urls into tags.
To substitute account numbers that aren't in urls, you simply
substitutes account numbers if they don't start with a "/", as you
have been t
I'm a little bored, so I wrote a function that gets elements
and puts them in a dictionary. Missing elements are just an empty
string.
http://gist.github.com/78385
Usage:
>>> d = process_finding(findings[0])
>>> ", ".join(map(lambda e: d[e], elements))
u'V0006310, NF, , , GD, 2.0.8.8, TRUE, DTBI
So you want one line for each element? Easy:
# Get elements
findings = domDatasource.getElementsByTagName('FINDING')
# Get the text of all direct child nodes in each element
# That's assuming every child has a TEXT_NODE node.
lines = []
for finding in findings:
lines.append([f.firstChild.d

It looks you're using an unnecessary extra loop.
Aren't the contents of fname sim
You're making it more complicated than it needs to.
Also, you first used binnum then binum, and you didn't define binsum.
It could easily be done like this:
binnum = raw_input("Please enter a binary number: ")
decnum = 0
rank = 1
for i in reversed(binnum):
decnum += rank * int(i)
rank *

Here's a simple repositioning code given that you already have the
fields extracted.
All files have to have equal dimensions.
file1 = [["1a1", "1b1", "1c1",], ["2a1", "2b1", "2c1"],]
file2 = [["1a2", "1b2", "1c2",], ["2a2", "2b2", "2c2"],]
files = [file1, file2]
out_lines = []
for column in range
For example, if you have input files:
file1:
1a1 1b1 1c1 1d1 1e1 1f1
2a1 2b1 2c1 2d1 2e1 2f1
3a1 3b1 3c1 3d1 3e1 3f1
file2:
1a2 1b2 1c2 1d2 1e2 1f2
2a2 2b2 2c2 2d2 2e2 2f2
3a2 3b2 3c2 3

Hi,
This behavior was totally unexpected. I only caught it because it was
the only thing I changed.
>>> class foo:
... def __init__(self, lst=[]):
... self.items = lst
...
>>> f1 = foo()
>>> f1.items
[]
>>> f1.items.append(1)
>>> f2 = foo()
>>> f2.items
[1]
Huh? lst is a refer
It looks way too simplified. I have no idea where the problem is.
Would you mind showing the script?

Hi,
I was wondering why this happens. I was trying to create a list of lists.
>>> d = [[]]
>>> d[0][0]=1
Traceback (most recent call last):
File "", line 1, in ?
IndexError: list assignment index out of range
>>> d
[[]]
What's wrong with that?
However:
>>> d[0].append(1)
>>> d
[[1]]

With the python version, the line below only works if there are three
fields in line.
(first, last, passwd) = line.split()
