This is cool I didn't know you could do that.

SyntaxError: assignment expression cannot be used in a comprehension iterable expression

Yeah but... This is just a simple one-liner. So it's still pretty readable, for me at least

It's not THAT bad at the end of the day 😅

You can avoid this now with the walrus operator

This is like what I did, but in one line.

Why did I not think of this...

same thing as drhrich but you avoid subtracting 1 to len(num)-y by passing 1 to enumerate (enumerate has a parameter "start" to start the enumeration at that number)

Python noob here, I gotta say Python one-liners like list comprehension are starting to look pretty understandable (at this level of complexity, at least...)
But cramming logic that repeats on each 'x' doesn't look good for Big O, for sure.

Please mark your post as having spoiler content next time. Your post was visible in the homepage discourse.

But seriously, what scares me is the number of cheerful comments.
We are in deep trouble.
