Reason: if let's say + 25 squares (number of squares) were passed, that is the total squares (split pieces) that the image is supposed + to be split into. As it is known, a 2D shape has a height and a width, and in this case the program thinks of it + as rows and columns. Rows multiplied by columns is equal to the passed squares (number of squares).

With left, top, right, bottom, = 0, 0, x_frac, y_frac, the program sets these variables to create the initial + square (split piece). Explanation: all of these 4 variables start at the top left corner of the Image, by adding + value to right and bottom, it's creating the initial square (split piece). + + 5. In the for loop, it keeps adding those squares (split pieces) in a row and once (index + 1) % xy == 0 is + True, it adds to top and bottom to lower them and reset right and left to recreate the initial space between + them, forming a square (split piece), it also adds the newly created square (split piece) into the new_imgs list + where it stores them.
