Question 5 - MCQ Questions (1 Mark each) - Chapter 10 Class 11 - Tuples and Dictionaries

Which of the following is the correct form of using dict()?

(a) >>>dict([(‘a’, 45),(‘b’,76)])

(b) dict({‘a’: 45,‘b’:76})

(c) dict(‘a’= 45,‘b’=76)

(d) All of these

Answer:

-lock-

The dict() function can take different types of arguments to create a dictionary object in Python.

The dict() function can take one of the following types of arguments:

• A sequence of tuples , where each tuple contains a key and a value. For example, dict([(‘a’, 45), (‘b’, 76)]) means that the key ‘a’ has the value 45 and the key ‘b’ has the value 76. The function returns a dictionary object with these key-value pairs.
• A mapping object , such as another dictionary , where each key-value pair is copied to the new dictionary object. For example, dict({‘a’: 45, ‘b’: 76}) means that the key ‘a’ has the value 45 and the key ‘b’ has the value 76. The function returns a dictionary object with these key-value pairs.
• Keyword arguments , where each argument is a key followed by an equal sign and a value . For example, dict(‘a’= 45,‘b’=76) means that the key ‘a’ has the value 45 and the key ‘b’ has the value 76. The function returns a dictionary object with these key-value pairs.

Therefore , all of these forms are valid ways of using the dict() function in Python. 

So, the correct answer is (d) All of these.
