does python always have a decimal after a math problem

Question

when I answered a question it had 2 options 6 and 6.0 i answered with 6 but why was 6.0 the right answer

Answer 1

int != float

Answer 2

No, it depends on the situation. Decimals tipically appear with divisions (e.g. 5/2 == 2.5) or when other decimals are involved (e.g. 1 + 1.0 == 2.0).
