Mysterious non-module A.sys

I have a package A containing a null __init__.py and a simple module B.py

C:\code>cat A\B.py
import sys
print __file__
print sys.modules.key s()

C:\code>python -c"import A.B"
['copy_reg', 'A.B', 'locale', '__main__', 'site', '__builtin__', 'encodings',
'os.path', 'A.sys', 'encodings.code cs', 'ntpath', 'UserDict',
'encodings.exce ptions', 'nt', 'A', 'stat', 'zipimport', 'warnings',
'encodings.type s', '_codecs', 'encodings.cp12 52', 'sys', 'codecs', 'types',
'_locale', 'signal', 'linecache', 'encodings.alia ses', 'exceptions', 'os']


where does A.sys come from? I tried an experiment and it seems that it's the
import statement in B.py so if I changed that to import sys,socket I also get
A.socket so I assume it's the import within import that causes these strange
modules to appear.

Strangely, attempts to import A.sys fail and its value in sys.modules is None.
What is the entry for?

I am having a hell of a time with what I think is a very simple query: It won't actually insert a new record into the specified table, but returns no error, in fact it returns "1" (or true) that the query was successful. Things to know: 1. id field is auto-incrementing primary key 2. Other queries SELECT, UPDATE, and DELETE all work no problem 3. INSERT works via phpMyAdmin 4.

Can anyone help with a mysterious problem that has arisen since 'upgrading' from 8 to The situation is this: Queries that worked fine under 8 are now producing *really* strange results under The queries all involve functions, including built-in functions like NVL. The strangeness is that less than the expected number of rows is returned *or* and ORA-01422 is generated. Here's an example:

Hi, I recently started using VC7.1 (upgraded from VC6). I've noticed that when stepping through code, some of the values of my variables make no sese at all. For instance, I had some code like this: int i = 1, j =1 ; for ( MyClass::ResultType::const_iterator ResultIt = ShowAll.getResults().begin(); ResultIt != ShowAll.getResults().end(); ++ResultIt, i++ ) {

Hi, In continuation of the thread I made "perhaps a stack problem? Long calculations - strange error?", I think I now got a "stable" error, meaning that the error always seem to come here now (tried: visual studio 2005 + linux/macintosh gcc)... That's a pretty good thing. I think the error still appears using both gcc and visual studio 2005. Everything is standard C (ANSI C ?? I don't know the difference) - but since so many functions...

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,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers. The idea...
