Detailed answer by teachoo

  • A dictionary is a collection of key-value pairs that are unordered, changeable, and indexed. 
  • There are many built-in functions/methods that can be used to manipulate dictionaries in Python. 
  • In this question, we are using the built-in methods copy() and clear() on a dictionary object. The syntax of these methods are:



where, dictionary is the original dictionary. The method copy() returns a shallow copy of the dictionary , which means it creates a new dictionary with the same key-value pairs as the original dictionary , but does not copy the references to the values. The method clear() removes all the key-value pairs from the dictionary and makes it empty.

  • Now that we know these concepts, we can proceed to find out the output of the code. We will follow these steps:
    • First, we will create a dictionary with three key-value pairs and assign it to the variable d using the statement d = {"name": "Ravi", "age": 20, "city": "Delhi"} .
    • Next, we will call the method copy() on d and assign the result to the variable d1 using the statement d1 = d.copy() . This will create a new dictionary with the same key-value pairs as d and assign it to d1. The dictionaries d and d1 will have different memory locations and any changes made to one will not affect the other.
    • Then, we will call the method clear() on d1 using the statement d1.clear() . This will remove all the key-value pairs from d1 and make it an empty dictionary. The dictionary d will remain unchanged.
    • Finally, we will display the values of d and d1 using the statements print(d) and print(d1) . This will print:

{"name": "Ravi", "age": 20, "city": "Delhi"}


  • Therefore, option A) is the correct answer.

So, the correct answer is 

A) {“name”: “Ravi”, “age”: 20, “city”: “Delhi”}
