all your lines are indented which the shouldnt be. Also its kind of unclear what the code is supposed to accompish. You are storing the matrixes as string and you have i variable implemented before the loop and you are checking if first letter in the string is equal to integer 0

I found the right code https://code.sololearn.com/cksr0eLD8HtW/#py One of the wrong codes was because I wanted to replace "len" with another way to find length of string

The goal of this code is to find out whether 2 matrix can be multiply or not The mathematical rule is columns of matrix "a" should be equal to rows of matrix "b"
