I am getting this index error for an image size 882 x 786 - IndexError: index 786 is out of bounds for axis 0 with size 786

I have pasted the code below -
<pre lang="Python">
    for x in range(width):
       for y in range(height):
          saturation_pink = saturation_pink + result_pink[x][y][1]*(27 - result_pink[x][y][0])

What I have tried:

I tried the above code with 'width-1' and 'height-1' as well. But I still keep getting the same error

What are the values of width and height, and the dimensions of result_pink?

Indexes in Python (like most other languages) start at zero, and run to the number of elements minus one.
So a three element array arr would have legitimate indexe of 0, 1, and 2 only - any other value is outside the bounds of the array and will cause an error.

In this case, you have probably muddled up width and height: should x be width related, or y, and do width and height contain the right values?
What did the debugger show you was going on?
