Just out of curiosity, is there any way to get the name of a
lambda expression? Lambdas are anonymous functions, so it's a
stupid idea to get the name of it. But if it's possible, how
could I?
Let's take a simple example:
foo = lambda:None
foo.__name__(or foo.func_name) returns '<lambda>'.
I'm looking for a way to return 'foo', instead of '<lambda>'.

Hi guys,
I'm a little worried about the expected disappearance of lambda in
python3000. I've had my brain badly broken by functional programming
in the past, and I would hate to see things suddenly become harder
than they need to be.
An example of what I mean is a quick script I wrote for doing certain
actions based on a regexp, which I will simlify in this instance to
make the pertanant points more relevent.

I thought it might be useful to put the recent lambda threads into
perspective a bit. I was wondering what lambda gets used for in "real"
code, so I grepped my Python Lib directory. Here are some of the ones I
looked, classified by how I would rewrite them (if I could):
* Rewritable as def statements (<name> = lambda <args>: <expr> usage)
These are lambdas used when a lambda wasn't needed -- an anonymous
function was created with...

Hi,
I cannot find the way to do generic lambda functions using the lambda
syntax in python. I am probably missing a point.
For example, the code
# f = lambda : print "hello"
# f()

I've been reading the recent cross-posted flamewar, and read Guido's
article where he posits that embedding multi-line lambdas in
expressions is an unsolvable puzzle.
So for the last 15 minutes I applied myself to this problem and come up
with this off-the-wall proposal for you people. Perhaps this idea has
been proposed before, I don't know.
The solutions I have seen all assume that the lambda must be completely
inlined within the...

How does the lambda library actually works. How does it know how to
evaluate _1, how does it recognize _1 as a placeholder, how does it
then calculate _1+_2, or _1+2 etc. The source files seem a bit
complicated so any explanation would be appreciated.
Thanks

I am never redefining the or reassigning the list when using validate
but since it spits the modified list back out that somehow means that
the modified list is part of the environment and not the old one.
i thought what happend inside a function stays inside a function
meaning what comes out is independent of what comes in.
Meaning if I want the list I send as a parameter to the function I
have to do x = func(x) and not just func(x) and x...

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...

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,...
