Some of what I read makes me chuckle.
Yes, large units of code, and even smaller ones, may be a chore to figure
out. Arguably harder when you use indentation and the next/last parts are
not even on the same screen as the rest. Sometimes you want to use a
split-screen in some editor to line up the

Many of those 4.8K "users" might be using indirectly via some other dependency
- I'm not sure how GitHub calculates "used by", but even if it were a direct
dependency, one has no idea if it's actually being used or not. so I tend not
to worry about such things. My distlib library has only 2 star
Stefan,
Agreed that writing code to handle all possible eventualities is usually
overkill and results in bloated software delivered very late or not at all.
My point is that often OTHERS start adding requests afterward that seem
trivial to THEM as they have no idea what it takes. I have often don
The topic of looping and our current discussion stimulates me to ask if
someone has categorized the uses of loops and it seems something obvious.
Once you know what kinds of loopy looping there are, it can get easier to
decide which, if any, of the methods to set up a loop make more sense.

An inconsistency that I have been able to notice is this:
someone suggests to remedy the absence of the do-while with:
while True:
...
if condition:
break
the problem arises if the while has an else of its own because the break
not only blocks the while loop but

Because it is very hard to spot or distinguish from a normal
while loop.
while condition ;
Is a valid (and fairly common) loop in C
so code that has
do{
code
}
while condition;
