Hello,
I have a request.
Would it be possible to include `follow_wrapper_chains` and `skip_bound_arg`
arguments to higher level functions of `inspect` module?
Would exposing them, but setting defaults to what they currently are, be
possible?
I sometimes need:
* `getcallargs`, but with
def powers_of_2_in(n):
s = 0
while n % 2 == 0:
s += 1
n = n // 2
return s, n

Yeah, I have been hearing that people are having troubles converting, but I
have only used argparse - got lucky there I guess.
I am thinking just making the function which spits the class out. Maybe not
very optimised solution, but simple.
Argument parsing in my case is very far from being a bo

Hi all,
I have a situation, maybe someone can give some insight.
Say I want to have input which is comma separated array (e.g.
paths='path1,path2,path3') and convert it to the desired output - list:
import argparse
parser = argparse.ArgumentParser()
parser.add_argument('paths', type=lambda x: li
Thank you.

What I am interested in is a callback.
Preferably just after methods get bound. So in `object.__new__`.
I have done it via metaclass, but it is not ideal as there would be too much
overhead.
I think what I am looking for is custom method binding.

In case someone is actually going to execute the code, there is a bug:
`set` need to be wrapped in `len` for criteria args.

So there is a method __set_name__ which is called on class creation.
The functionality that I am interested in is not retrieving name, but the fact
that it also receives `owner` argument.
Thus, allowing simulation of bound class method.
I was wandering if there is an equivalent functionality of
The specific situation was related to truth values and following out of that my

So one of the specific examples:

Fair point.

to even convey what I mean. Bad naming didn’t help ofc, but if it was something
that is needed I think it would have clicked much faster.

applied to many bits.
This is more in line with cases that `any` and `all` builtins are used.

Benchmarks:

test2 = [True] * 100 + [False] * 2

Both of the above would evaluate to true.
Well, it depends how you interpret it.
In binary case it reads: “exclusively one positive bit or the other, but not
both”
In this case one could read: “exclusively one positive se

Hi All,
I think it could be useful to have `xor` builtin, which has API similar to the
one of `any` and `all`.
* Also, it could have optional second argument `n=1`, which indicates how many
positives indicates `True` return.
* For complete flexibility 3rd argument could indicate if `the number`
I don’t think there i a simple answer to this, although if you find something
interesting, please share.
From my experience, industry is applying variety of testing methods. Starting
from lowest level components and implementing unit tests, finishing with
end-to-end testing platforms.
https://
y = test1(*[a for a in st])
y = test1(*st)
Maybe any of these would be ok for you?

It is by design. `sorted` returns a list, while `reversed` returns an iterator.
Iterators are exhaust-able, and not reusable. So be mindful of this and if you
are going to "re-use” the sequence returned by iterator, convert it to list
first.
Have a look at `itertools` library, which contains a
The issue was more of a wrapping around numpy array. Found the solution
already. Unfortunately, there is no equivalent to __getattr__, the only way is
to dynamically define them from meta. It seems it’s pretty standard to just
have a collection of special method names and using them for similar
Tried exactly that and didn’t work. Neither __getattr__, nor __getattribute__
of meta is being invoked.
