no_14

Given a list of ints, return true if it contains no 1’s or it contains no 4’s.

no_14([1, 2, 3]) -> true
no_14([1, 2, 3, 4]) -> false
no_14([2, 3, 4]) -> true

This exercise was taken from codingbat.com and has been adapted for the Python language. There are many great programming exercises there, but the majority are created for Java.

Starter Code

from typing import List


def no_14(nums: List[int]) -> bool:
    pass


result = no_14([1, 2, 3])
print(result)
