Given the following code, what will be the output?

booked_slots = {"9AM": True, "10AM": False}
requested_slot = "10AM"

BSlot Booked

CKeyError

DNo output

Step-by-Step Solution

Solution:

Step 1: Understand the dictionary and requested slot
booked_slots maps times to True (booked) or False (free). "10AM" is False, meaning free.
Step 2: Evaluate the condition
booked_slots.get("10AM", False) returns False. 'not False' is True, so it prints "Slot Available".
Final Answer:
Slot Available -> Option A
Quick Check:
False means free, so output is Slot Available [OK]

Quick Trick: False means free slot, so print available [OK]

Common Mistakes:

Assuming True means available instead of booked
Expecting KeyError when key exists
Ignoring default value in get()
