There's a parallel here. Since a for-else loop is basically useless
without an if-break construct inside it, the else clause can be
thought of as the else on a massive if/elif chain:
if stuff[0].is_good:
print("This item is good", stuff[0])

You get the idea.
If I really want to remember what this construct means, I remind myself
that `else` here really means `no break`. Would have been better if it
had been spelt `nobreak` or similar in the first place.

I want to make a little survey here.
Do you find the for-else construct useful? Have you used it in
practice? Do you even know how it works, or that there is such a thing
in Python?
I have used it maybe once. My issue with this construct is that
calling the second block `else` doesn't make

For those of us who don't know would you be kind enough to do a cost
comparison of Matlab vs Python licenses?

Here's one way, one step at a time:

array([[ 1, 2, 3, 4, 5, 6],
[ 7, 8, 9, 10, 11, 12]])
, each is 3 rows.
I want to use these to construct matrix mat, which is
[[v1,v2],
[v3,v4]]
So the resulting matrix is as shown in the link. i.e.
it will be 6 rows and 2 columns.
This is what I tried:
import numpy as np
v1=np.array([1,2,3]);
v2=np.array([4,5,6]);
v3=np.array
construct matrix mat, which is
[[v1,v2],
[v3,v4]]

If you see a discussion as a zero-sum game – like a coin toss, where one
person's win can only be at the expense of someone else's loss – then I
fear this isn't going to be productive.

That was an unfortunate example for you to chose since it
directly contradicts your claims.
Read that quote again. You are a programmer. You should
understand logic. Please explain how acknowledging *one*
