How to remove list elements given set of indexes?

Is there an efficient way to solve the following problem:

lst = [1,2,3,4,5]
indexes_to_remove = [0,2,4]

#result
lst = [2,4]

Answer 1

If speed is of concern, use delete function from numpy module:

import numpy as np

lst = [1,2,3,4,5]
indexes_to_remove = [0,2,4]

lst = np.array(lst)
indexes_to_remove = np.array(indexes_to_remove)

lst = np.delete(lst, indexes_to_remove)

Timing test for lst = list(range(10000)) and indexes_to_remove = list(range(0, 2000, 2)) shows numpy.delete is about 1000X faster than list comprehension.
