I think it's better To determine whether a key is in a dictionary

Example: nums = { 1: "one", 2: "two", 3: "three", } print(1 in nums) print("three" in nums) print(4 not in nums) >>>true >>>false >>>true But we can write: nums = { 1: "one", 2: "two", 3: "three", } print(1 in nums.keyworld) print("three" in nums) print(4 not in nums.keyword) And now: >>>true >>>true >>>true If I were a Python developer I would have added this section to the language.
