Can someone explain how is this length calculated

Question

Something similar came up in one of the challenges, so I tried to play with it hoping I’d figure it out but I still don’t have a good understanding so reaching it to community for help

X= [[0],[1]]
print(list(map(str, x)))
print(‘’.join(list(map(str, x))))
print(len(‘’.join(list(map(str,x)))))

I understand the output of first and second line:
>>[‘[0]’, ‘[1]’]
>>[0][1]
>>6

But don’t understand how the last line (length of )6 is calculated. I’d appreciate a simple explanation.

Answer 1

handled as string? 6 characters, [ ] included.

first one makes items in list strings, second joins contents of lists as a single string and the third counts its lenght in characters

Answer 2

Thank you! That makes sense now!
