How to change the value of certain indices of a numpy array to 0?

Question

I am trying to set the values of array elements to 0 in a numpy array +/- 50 from a certain index. I have a numpy array named proc_ranges and I am using numpy.put() to do this:

proc_ranges = numpy.put(proc_ranges,[closest_point_index-50:closest_point_index+50], 0)

I am getting a syntax error at the ":", but this seems like the correct way to do this according to the syntax outlined here

Answer 1

You could just do this instead

proc_ranges[closest_point_index-50:closest_point_index+50] = 0

Yeah, you just need to make sure that the value closest_point_index-50 or closest_point_index+50 do not exceed the array size.
