Exclude words with specific endings from list

[Epileptiker]

list1 = [item for item in list1 if not item.endswith("-s") and not item.endswith("-en")]

Okay i just tried it by copying this code in my script right here, but when i run it, it still posts words with these two endings. No error message. What have i done wrong? ...

with open('list2.txt') as infile:
    list2 = ast.literal_eval(infile.read())
    list2 = [item for item in list2 if not item.endswith("-s") and not item.endswith("-en")]
