Sort list by given order of indices

Question

I have a list of lines read from a file. I need to sort the list by time stamp. I have parsed out the time stamp using regular expressions and place them into a separate list. T

Answer 1

If you want to sort the original list because you, say, hald references to it elsewhere, you can assign to it the sorted list:

my_list[:] = [my_list[i] for i in sorted_indexes]  # [:] is key!
