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 ind O The code is correct and would always perform faster than the builtin key lookup provided by Python.
