You are now working for Prof. Midas on a research project. You are given this piece of code to review which is intended to be a better and faster implementation of a function that checks whether a given key is in a dictionary (i.e., key lookup). You have to present your findings to Prof. Midas. Select all the findings which you will NOT present (i.e., select all answers which are FALSE). def key_in_dict(d, k): for item in d: if k == item: return True return False O This code would always be slower than the builtin key lookup Python provides. O A key lookup in a dictionary in Python is generally faster than determining whether a value is in a list. O This code is way faster and will be included in the next version of Python (version 4.1). O The code is incorrect from a functional perspective, the True and False should be switched. O This code could be replaced with one line: return k in d O The code is correct and would always perform faster than the builtin key lookup provided by Python.
