  • Description

    Just converting the int into string, reversing it by ( [::-1] ) and finaly converting again to an int.

     Code 
    def reverse_int(num):
    return int(str(num)[::-1])
     Test Cases 
    import codewars_test as test
# TODO Write tests
import solution # or from solution import example

# test.assert_equals(actual, expected, [optional] message)
@test.describe("Example")
def test_group():
    # Why do so many people not put Python testcases into this nice format?
    @test.it("test case")
    def test_case():
        test.assert_equals(reverse_int(12345), 54321)
        test.assert_equals(reverse_int(0), 0)
