str.translate requires dict maps unicode ordinals other unicode oridinals (or none if want remove character). can create so:

old_string = "file52.txt" to_remove = "0123456789" table = {ord(char): none char in to_remove} new_string = old_string.translate(table) assert new_string == "file.txt" 

however, there simpler way of making table though, using str.maketrans function. can take variety of arguments, want 3 arg form. ignore first 2 args mapping characters other characters. third arg characters wish remove.

old_string = "file52.txt" to_remove = "0123456789" table = str.maketrans("", "", to_remove) new_string = old_string.translate(table) assert new_string == "file.txt"
