list(range(11)[10:0:-2]

This code will result in a syntax error because the closing square bracket is missing. Here is the corrected code:

list(range(11)[10:0:-2])

This code will create a list of numbers from 10 to 1 (excluding 0) with a step of -2, which means that it will skip every other number and go backwards. The resulting list will be [10, 8, 6, 4, 2].
