If I remember right, the solution was written in Python 2. In that version of Python zip() returns a list. In Python 3 zip() returns a zip object instead, so you will need to convert it into list in order to concatenate it with lists.
board + [*zip(*board)] + blocks can help resolve this.

The solution was written in Python 2. It differs from Python 3. In Py2 / denotes integer division, not float division.

This solution is not working for me in VS code Python 3.94 Win 10:

TypeError: can only concatenate list (not "zip") to list

Any suggestions why? Thanks.

return not filter(lambda x: set(x) != set(range(1, 10)), board + list(zip(*board)) + blocks) Working now

return '{:02}:{:02}:{:02}'.format(s / 3600, s / 60 % 60, s % 60)
This statement may have a decimal bug，so we can use return '{:02}:{:02}:{:02}'.format(s // 3600, s // 60 % 60, s % 60)

I do not understand how the Kata description " How many years does the town need to see its population greater or equal to p = 1200 inhabitants?" when we have used population < target.

Man, this thing is so beautiful, and researching this has teached me a lot, so thank you.
