I'm trying to use signal.alarm to stop a run-away os.system command.
Can anyone exlain the following behavior?
Given following the trivial program:
import os
import signal
def timeoutHandler(signum, frame):
print "Timeout"
raise ValueError
signal.signal(signal.SIGALRM, timeoutHandler)
I have read in a file and need to get the number of lines.
cpn_file = open('Central Part number list.txt')
cpn_version = cpn_file.read().split('\n')
I want to know the number of elements in cpn_version.

PyParsing rocks! Here's what I ended up with:
def unpack_sql_array(s):
import pyparsing as pp
withquotes = pp.dblQuotedString.setParseAction(pp.removeQuotes)
withoutquotes = pp.CharsNotIn('",')
parser = pp.StringStart() + \
pp.Word('{').suppress() + \
pp.
A fetchall() call causes the above error. There must be some non-utf8 chars
in the table in question and - indeed - there very likely are: The table
contains pathnames of files on the harddisk of a German "speaking" PC.
What I have already done to try to overcome this is:

XPN (X Python Newsreader XPN) is a multi-platform newsreader with
Unicode support. It has features like scoring/actions, X-Face and Face
decoding, muting of quoted text, newsrc import/export, find article and
search in the body, spoiler char/rot13, random taglines, and
configurable attribution line

CL, after you install py_win32 on windows you should look for a module
called "excel*.py" under your ${PYTHONHOME} directory. They have a

You know how you can specify that stderr, stdin, stdout should be

1. Why not to simplfy the problem. You can extract values from the
dictionari in python (this is fast). Put them in a list (fast). Pass
the list to the extension, handle it and return to python. etc.
2. Use Pyrex.
