I have a python file script that I want to run many times. but any time I run it the return value is different but the input is the same:

below code show it:

from typing import Iterable
def get_hash(hash_string: Iterable[str]) -> str:
    hash_string.sort()
    return str(hash(tuple(hash_string)))

sample_list = ['00b3ee037a1cfba5158e7c9fad04ced03b92fe3b', '02db69a00d40834ab095cbbbe18fe8945229df9b']
get_hash(sample_list)

Any time I run this script the result is different!!!

    Because hash computes a hash based on the object and the tuple(hash_string) is a different object every time (see here). What you need is a hash function like MD5 see here Commented Jun 27, 2022 at 14:19
  • It's supposed to change every time you run your program. See peps.python.org/pep-0456 Commented Jun 28, 2022 at 2:24
