I am doing some Codewars practice and got this problem. The goal is to determine if the word provided “text” ends with “ending”. The solution i have works with every test case but (sumo, omo). For some reason, the for loop returns to 0 after 1. This does not occur with any other test case.

def solution(text, ending):
    text_list = list(text)
    ending_list = list(ending)
    results_list = []
    text_list.reverse()
    ending_list.reverse()

    if len(text_list) >= len(ending_list):
        for i in ending_list:
            num = ending_list.index(i)
            if ending_list[num] == text_list[num]:
                results_list.append(0)
                print(num)
            else:
                results_list.append(1)
            
        if sum(results_list) == 0:
            return True
        else:
            return False
    else:
        return False

Above is my Code

from solution import solution
import codewars_test as test
from random import randint

fixed_tests_True = (
    ( "samurai", "ai"    ),
    ( "ninja",   "ja"    ),
    ( "sensei",  "i"     ),
    ( "abc",     "abc"   ),
    ( "abcabc",  "bc"    ),
    ( "fails",   "ails"  ),
)

fixed_tests_False = (
    ( "sumo",    "omo"   ),
    ( "samurai", "ra"    ),
    ( "abc",     "abcd"  ),
    ( "ails",    "fails" ),
    ( "this",    "fails" ),
    ( "spam",    "eggs"  )
)

@test.describe("Fixed Tests")
def test_group():
    @test.it("True Cases")
    def test_case():
        for text, ending in fixed_tests_True:
            test.assert_equals(solution(text, ending), True)
    @test.it("False Cases")
    def test_case():
        for text, ending in fixed_tests_False:
            test.assert_equals(solution(text, ending), False)

Above is the test case provided.
