C4 : W1 : A1 : Ex 3 - Z's mean is incorrect

I don’t quite understand how ‘stride’ is included in the calculation of vert_start and horiz_start. And do the calculations of these 2 variables include the respective for-loop variables?

Ok I have solved my issue.

Thanks for your report.

Hi Anish … I am getting the same error. How did you solve the issue ?

Maybe this guide helps.

Thank for your help. Issue resolved.
