Question

What is the output produced by the following statements: 2

D= {2: (‘a’,’b’,’c’) , 3:[‘x’,’y’,’z’], ‘Id’: 3, ‘No’: 2}
a) print(D.keys( ))
b) print(D.pop(2))
c) print(D.get(3)
d) ‘a’ in D

Answer 1

The code snippet in question demonstrates dictionary operations in Python, including getting dictionary keys, popping an item, retrieving a value with a key, and checking for a key's existence.

Step-by-step explanation:

The student is asking about the output of a given Python code snippet that involves dictionary operations. Below are the explanations for each line of the code:

• D.keys(): This will print out all the keys of the dictionary D. So the output will be dict_keys([2, 3, 'Id', 'No']).
• D.pop(2): This will remove the key-value pair with the key 2 from the dictionary and return the value. The output will be ('a', 'b', 'c').
• D.get(3): This will print the value associated with the key 3 in the dictionary. The output will be ['x', 'y', 'z'].
• 'a' in D: This checks if 'a' is a key in the dictionary D, which it is not, so the output will be False.
