As much as I agree that the function needn't be in the base of python, I
can easily follow the OP's logic on the function name.
With two items in the iterator, it is a standard binary exclusive or.
It is true if one of but not both
I don't think an exclusive-or/truthy-entries-count-checker needs to be a
builtin by any stretch.
>>> def xor( iterable, n = 1 ):
... return sum( map( bool, iterable ) ) == n
Or if you insist on short circuiting:
>>> def xor_ss( iterable, n = 1 ):
... for intermediate in itertools.accumulat

is effectively locked/atomic on post-3.10 interpreters, though this is
neither portable nor guaranteed to stay that way into the future

I wanted to provide an example that your claimed atomicity is simply wrong,
but I found there is something different in the 3.10+ cpython
implementations.
I've tested the code at the bottom of this message using a few docker
python images, and it appears there is a difference starting in 3.10.0

Python doesn't care what an expression returns.
You've written an expression that returns the value of the 'clear' function
that is bound to that particular list.
The interpreter doesn't know or care if accessing that 'clear' attribute on
the class returns a function or for some reason triggers a

if you get to the point where it's hard to tell which else lines up with
which if or for statement, I would suggest breaking things out into
well-named helper functions rather than worrying over orderin
pkg/graph.py:
from graphing_module_b import plot, axis
pkg/foobar.py:
from .graph import plot, axis
Would it be sufficient to use a file for indirection?

You may want to use `#!/usr/bin/env python3` instead.
There is a concept in python called the virtual environment. This used to
be done with a tool called virtualenv in python2, and is now done mainly
through a venv module in python3.
A virtual environment goes into a directory of your choosing a

You're missing a comma, and python automatically concatenates adjacent
strings.

By his reasoning it simply shouldn't exist. Instead you would access the
information only like this:
with open("myfile.dat") as f:
data = f.read()
Which is my preferred way to work with resources requiring cleanup in
python anyways, as it ensures I have the least chance of messing things up,

Load up your interpreter and play with it interactively. Remember the
dir( object ) command will give a full listing of the attributes of
any given object. Looking at object.__doc__ will give you the
documentation. There's probably something in there to hide the window
if that

The interactive runtime requires the OneChar definition, and the compilation
