I was going to file this as a bug in the tracker, but maybe it's not really
a bug. Poor Python code does what I consider to be unexpected. What's your
opinion?
With Python 2.3.2 (but also happens with 2.2)
An import within a function that shadows a global import can raise
UnboundLocalError. I think the real problem is that the the local 'import
sys' is seen as occuring after the use of sys within this function, even
though sys is...

I'm trying to define a function that prints fields of given widths
with specified alignments; to do so, I wrote some helper functions
nested inside of the print function itself. I'm getting an
UnboundLocalError, and after reading the Naming and binding section in
the Python docs, I don't see why.
Here's the error:
>>> fieldprint(, 'rl', )
Traceback (most recent call last):
File "<stdin>", line 1, in ?

Hi,
I am trying to work out why I get UnboundLocalError when accessing an
int from a function where the int is at the global scope, without
explicitly declaring it as global but not when accessing a list in
similar circumstances.
The documentation: http://docs.python.org/ref/naming.html does not give
me enough info to determine why the difference exists as it does not
seem to mention types at all..

hi all
why it generates an "UnboundLocalError" when I do the following:

def main():
number = number()
number_user = user_guess()
while number_user != number:

Hi,
i have a problem, the source of which is probably the fact, that i have
not understood how to declare global variables - I use the Jython
compiler, but i think this is a Python issue...
First of all, i don not use any classes in this module. The problem is,
that i declare and instantiate some vars outside the functions (global
ones), but when i use them inside the functions, i get an
"UnboundLocalError" error.

isPrime works when just calling a nbr but not when iterating on a
list, why? adding x=1 makes it work though but why do I have to add
it?
Is there a cleaner way to do it?
def isPrime(nbr):
for x in range(2, nbr + 1):
if nbr % x == 0:

That's invalid C (you cannot declare variables in the "for" statement

I'd say it all follows from the fact that Python doesn't have variable

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
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,...
