Is there any python module to convert PDF files into text? I tried one piece of code found in Activestate which uses pypdf but the text generated had no space between and was of no use.
There is function in python called eval that takes string input and evaluates it.
>>> x = 1
>>> print eval('x+1')
2
>>> print eval('12 + 32')
44
>>>
What is Haskell equivalent of eval function?
I am using python lxml library to parse html pages:
import lxml.html
# this might run indefinitely
page = lxml.html.parse('http://stackoverflow.com/')
Is there any way to set timeout for parsing?
Hi folks,
I'm using the timeout parameter within the urllib2's urlopen.
urllib2.urlopen('http://www.example.org', timeout=1)
How do I tell Python that if the timeout expires a custom error should be raised?
Any ideas?
I have a list in python ('A','B','C','D','E'), how do I get which item is under a particular index number?
Example:
Say it was given 0, it would return A.
Given 2, it would return C.
Given 4, it would return E.
First of all, I get the name of the current window
win32gui.GetWindowText(win32gui.GetForegroundWindow())
k, no problem with that...
But now, how can I make an if with the result for having an specific string on it...
For example, the result gave me
C:/Python26/
How can I make an True of False for the result containing the word, 'python' ?
I'm trying with re.search, but I'm not being able to make it do it
Is there a way to get functionality similar to mkdir -p on the shell... from within python. I am looking for a solution other than a system call. I am sure the code is less than 20 lines... really I am wondering if someone has already written it?
hi, i am siva this is frist time taken the python programming language i have a small problem please help me the question is **Write two functions, called countSubStringMatch and countSubStringMatchRecursive that take two arguments, a key string and a target string. These functions iteratively and recursively count the number of instances of the key in the target string. You should complete definitions for
def countSubStringMatch(target,key):
and
def countSubStringMatchRecursive (target, key):

I have 4 reasonably complex r scripts that are used to manipulate csv and xml files. These were created by another department where they work exclusively in r.
My understanding is that while r is very fast when dealing with data, it's not really optimised for file manipulation. Can I expect to get significant speed increases by converting these scripts to python? Or is this something of a waste of time?
I've a python script that gives me 2 lists and another who is the reference(the time).
How can I create a graphic with the representation of my first list by the time. And same question for the second list. I need them on the same graphic.
list1 [12, 15, 17, 19]
list2 [34, 78, 54, 67]
list3 [10, 20, 30, 40] (time in minutes)
How can I create a graphic in png format with these lists?
Thanks

I use the following method to break the double loop in Python.
for word1 in buf1:
find = False
for word2 in buf2:
...
if res == res1:
print "BINGO " + word1 + ":" + word2
find = True
if find:
break
Is there better way to break the double loop?
What are my best options for creating a financial open-high-low-close (OHLC) chart in a high level language like Ruby or Python? While there seem to be a lot of options for graphing, I haven't seen any gems or eggs with this kind of chart.
http://en.wikipedia.org/wiki/Open-high-low-close_chart (but I don't need the moving average or Bollinger bands)
JFreeChart can do this in Java, but I'd like to make my codebase as small and simple as possible.
Thanks!
Ignoring all the characteristics of each languages and focusing SOLELY on speed, which language is better performance-wise?
You'd think this would be a rather simple question to answer, but I haven't found a decent one.
I'm aware that some types of operations may be faster with python, and vice-versa, but I cannot find any detailed information on this. Can anyone shed some light on the performance differences?
Is there any free Python to C translator? for example capable to translate such lib as lib for Fast content-aware image resizing (which already depends on some C libs) to C classes and files?
I'm looking for up-to-date documentation and tutorials on creating Python bindings for gobjects. Everything I can find on the web is either incomplete or out of date.
How can I find as many date patterns as possible from a text file by python? The date pattern is defined as:
dd mmm yyyy
^ ^
| |
+---+--- spaces
where:
dd is a two digit number
mmm is three-character English month name (e.g. Jan, Mar, Dec)
yyyy is four digit year
there are two spaces as separators
Thanks!

Is there any benefit in using compile for regular expressions in Python?
h = re.compile('hello')
h.match('hello world')
vs
re.match('hello', 'hello world')
I wanted to know if there was a way I can get my python script located on a shared web hosting provider to read the contents of a folder on my desktop and list out the contents?
Can this be done using tempfiles?
What tools are good to use for code analysis in python?
I have a large source repository split across multiple projects, and I would like to be able to run tools across the directories to see details like Cyclomatic Complexity, and perhaps be able to spot errors using static analysis.
Ideally, I would like to be able to produce a report about the health of the source code, so we can spot problem areas that need to be addressed.
