Hi people
Part of the reason I have started using Python (experience: 3 days) is that
I recognise the potential benefits in using it compared to writing C/C++
code. In particular, there are a couple of modules in an application that I
am writing that I have calculated will be up to ten times quicker to develop
(although it is hard to say at this stage), which is obviously quite
attractive.
The "problem" I have is relating to the...

Hi,
I am trying to use Python to do the following:
- read in an image in geoTIFF format
- extract the tags from the file
- do something interesting with the tags
I've read about the Python Imaging Library (PIL) which seems to do
what I need with TIFF files. I was wondering if anyone knows if this

Hi all.
Handling files is an extremely frequent task in programming, so most
programming languages have an abstraction of the basic files offered by
the underlying operating system. This is indeed also true for our language
of choice, Python. Its file type allows some extraordinary convenient
access like:
for line in open("blah"):
handle_line(line)

Hi,
I am having a problem with Python. I am new to Python as a programming
language, but I do have experience in other languages. I am
experiencing strange problems with File handling and wonder if anyone
else has seen this or knows what I am doing wrong. I am simply trying
to open a file for read and iterate through until the end of file. I am
able to do so without a problem, but here's the catch: The open
statement is only working on...

Hi all,
I've got two somewhat general questions related to exception handling
in C++. My usual programming language is the lovely and flexible
Python, but for various reasons, including the need to interface with
third-party libraries, get extra performance, etc. I have to use C++.
Now in Python, being a dynamically typed language, everything is
pushed to the run-time. Additionaly, since the language does not
guarantee deterministic...

Dear python experts,
I am new to python and this site, so I apologize if this is off topic (i.e. is it a SciPy question?). I will try to demonstrate my problem below:

from scipy import *
from scipy.stats import *

I am a little bit confused by all possibilities for exceptions handling
in Python (probably because I am not skilled enough??) I did try to
search trough this list and reading Python tutorial about Errors and
Exceptions but didn't find some "general" answer about exception
handling policy (strategy).
In the following example each row can IMHO raise an exception (if the
Firebird service is not running for example, if the database is...

There are situations where you want to retry/rerun the same code again (if
user wants) for unlimited times for a particular exception thrown. For
example in situations like there's no CD in the drive or some file is locked
by another process you want to display message dialog to user with "Retry"
and "Cancel" buttons (As Windows shows "Retry" option if no CD in drive) and
if user clicks "Retry" you want to run the same code again that...

I've some troubles getting my memory freed by python, how can I force
it to release the memory ?
I've tried del and gc.collect() with no success.
Here is a code sample, parsing an XML file under linux python 2.4
(same problem with windows 2.5, tried with the first example) :
#Python interpreter memory usage : 1.1 Mb private, 1.4 Mb shared
#Using http://www.pixelbeat.org/scripts/ps_mem.py to get memory

Python provides a quite good and feature-complete exception handling
mechanism for its programmers. This is good. But exceptions, like any
complex construct, are difficult to use correctly, especially as
programs get large.
Most of the issues of exceptions are not specific to Python, but I
sometimes feel that Python makes them more acute because of the free-n-
easy manner in which it employs exceptions for its own uses and allows
users...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
