Re: How to parse HTTP time header?

phi...@semanchuk.com (Philip Semanchuk) — Sun, 08 Nov 2009 04:19:11 UT

Sorry, my mistake -- 2616 != 2822. I'm not sure if there's something
in the standard library for parsing RFC 2616 dates.
When I faced the problem of parsing HTTP dates, I wrote my own
function although this was in an application that was deliberately
unforgiving of invalid input and therefore my code makes no allowances

The parsedate() function in the rfc822 module does this and claims to
be tolerant of slightly malformed dates, but that module is deprecated
as of Python 2.5 in favor of the email module which hopefully has an
equivalent function.

Re: Cancelling a python thread (revisited...)

pavlovevide...@gmail.com (Carl Banks) — Sun, 08 Nov 2009 03:27:52 UT

It doesn't sound like the thread is communicating with the process
much. Therefore:
1. Run the C code in a separate process, or
2. Create the thread from a C extension, maybe even straight from
ctypes, and kill it from C or ctypes.
Arguing that there are good reasons to allow killing threads isn't
going to get you very far. The language developers already know

More on canvas widget...
The Canvas widget should return objects and not simple tags/ids for
canvas items *OR* at least allow for me to add attributes to the
canvasitems "obj". I find that the id/tag system --while quite simple
and strait forward-- can really leave you with both hands tied behind
you back whilst suffering a wicked itch on the tip of your nose that

Cancelling a python thread (revisited...)

s...@pantoffel-wg.de (Sven Marnach) — Sun, 08 Nov 2009 02:04:04 UT

Hi,
the Python threading module does not seem to provide a means to cancel
a running thread. There are many discussions on the web dealing with
this issue and many solutions are offered, but none of them seems to
be applicable to my situation, which is as follows:
I have a C library which does some very computationally intensive

Re: PyQt processEvents not processing

pict...@gmail.com (DarkBlue) — Sun, 08 Nov 2009 02:16:50 UT

As per your suggestion I added a timer to the init part and now the
update works as expected , even without calls to processEvents.
self.myTimer = QtCore.QTimer(self)
QtCore.QObject.connect(self.my Timer,QtCore.SIGNAL("timeout() "),
self.doUpdate)
self.timerTime = 0
self.myTimer.start(2000)
Thanks

I'm not sure I understand this. How would you implement tagged integers
without encoding type information in bits of the pointer value?

1e7 is a way to express a float in science and math. Try float("1e7")

Re: How convert string '1e7' to an integer?

benjamin.kap...@case.edu (Benjamin Kaplan) — Sun, 08 Nov 2009 01:52:37 UT

Whenever you use that notation, you always get a float
10000000.0
So to convert '1e7' to a number, you need to use float('1e7') which
you can then convert to an int
10000000

Re: How convert string '1e7' to an integer?

gher...@islandtraining.com (Gary Herron) — Sun, 08 Nov 2009 01:50:53 UT

But 1e7 is a valid float, so this works:
>>> int(float('1e7'))
10000000
That has a problem though, if you surpass the ability of a float:
>>> int(float('1e20'))
100000000000000000000L
>>> int(float('1e30'))

In Python the e-form indicates a float, as does the presence of a
decimal point, but you can convert to float and then to int:
>>> int(float('1e7'))
10000000
