Solution

The result of the code will be True.

Here's the step by step explanation:

  1. A dictionary d is created with two keys: "john" and "mark", with corresponding values 40 and 30.

  2. The in keyword in Python is used to check if a specified key exists within a dictionary.

  3. The line print("john" in d) checks if "john" is a key in the dictionary d.

  4. Since "john" is indeed a key in the dictionary d, the output of the code will be True.
