Python - set list range to a specific value

Question

I need to set a subset of a list to a specific value based on a tuple with bounds (start,end).

Currently I\'m doing this:

indexes = rang         


        

Answer 1

Here is a more efficient version of the solution by @MartijnPieters using itertools.repeat

import itertools
lower, upper = bounds
upper += 1
my_list[lower:upper] = itertools.repeat('foo', (upper - lower))
