clean clean

I agree that it's not always good, but it's not always bad either. Just got to make sure it's clear, and you don't need to rewrite or change it later.

one line obssesive people >:(

wow!

Anyone knows what this part is doing "${COST_B%.*} + 1" ?

wow

Kind of neat.

Good explanation! Thank you

By using line[:] you're making a copy of the list. If you instead just use line, you're adding the same line to the board multiple times. In that case, when you change one element to O, it changes that element in every row of the board.

You can see more here: https://docs.python.org/3/faq/programming.html#how-do-i-copy-an-object-in-python

Why do I nedd to put "line[:]" instead of just "line" when i'm declarating board? With line it turn all the items into O's

Very nice use of the shift

I think the first "!" is to convert the pointer that strchr returns to a number(one if its a null pointer, and zero if the strchr found the specific character), so we can actually add to "int c". And the last "!", is to convert to the right number ,because null pointer was assigned to value one...

I assumed this based on sandoy's commentary... Might not be the right answer.

Could anyone explain to me what the "obj[i] = -~obj[i]" is doing here? I don´t understand the functionality of the - and the ~.

How can you pass the array that you made in the last line into the argument in the second line? I understand what you are doing... But I have never seen a structrure like this
