W3 Practice lab, In Compute gradient funct

Why my code is showing an “IndentationError: unindent does not match any outer indentation level”.

Can you please elaborate ?
probably you have made some mistake in spacing in the syntax

It means your code doesn’t have the correct indentation.

Python has extremely strict rules about how your code is indented, since this is how it defines blocks of code.

Please do not post your code on the forum. That breaks the course community standards.

If a mentor needs to see your code, we’ll ask you to send it via a private message.

I checked it many times, but i can’t find any error?

I think i have deleted the comments in code how to get back them?

Please check this out.
