You might try the os.path module and/or the glob module in the standard
python library.

Here's a function I wrote for checking remote or local file existence. It works for me but admittedly I haven't tested many cases with it. Also its currently specific to an http URI scheme.
def fileExists(self , fileUrlPath):
fileExists = False
if "http:" in fileUrlPath.low er():
#We don't want to open the file so ask the header if the
#file exists
urlParts = urlparse(fileUr lPath)
host = urlParts[1]
http = httplib.HTTP(ho st)
http.putrequest ("HEAD", fileUrlPath)
http.putheader( "Host", host)
http.endheaders ()
errorcode, errormessage, headers = http.getreply()
if errorcode == 200:
fileExists = True
else:
fileExists = path.exists(fil eUrlPath)
return fileExists

The idea was to *not* know the filenames beforehand, but instead get a
directory-listing. Which is impossible to get.

Hi,
I am working on converting Informix database to Postgre. I have one
question for fetching records using PostgreSQL. The record I am fetching
is a variable size text string. Before fetching the record, a
preallocated static buffer size will have to be declared beforehand in
the declaration section. Since the record sizes vary a lot, instead of
using the static buffer, is there a dynamic way to fetch these records?

Hi,
I'm starting a project that will work in many clients and a requiriment is a plataform agnostic system. The idea behind the project
is a winform client based interface with a webservice communication middle tier.
In .Net 2.0, it's very easy to develop and deploy for Windows. My question is about the initiatives to run complex .Net systems in
agnostic plataform way (like Linux). There's real perspectives to make this work fine (some...

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp

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,...
