Which of the following will delete key-value pair for key = “Name” from a dictionary D1?a. delete D1("Name") b. del D1["Name"] c. del.D1["Name"] d. D1.del["Name"]
Question
Which of the following will delete key-value pair for key = “Name” from a dictionary D1?a. delete D1("Name") b. del D1["Name"] c. del.D1["Name"] d. D1.del["Name"]
Solution
The correct option is b. del D1["Name"]
Here's why:
In Python, you can delete a key-value pair from a dictionary using the 'del' keyword followed by the dictionary name and the key in square brackets. So, if you have a dictionary D1 and you want to delete the key-value pair for key = “Name”, you would use the syntax: del D1["Name"]
Option a. delete D1("Name") is incorrect because 'delete' is not a recognized keyword in Python.
Option c. del.D1["Name"] is incorrect because there should not be a period after 'del'.
Option d. D1.del["Name"] is incorrect because 'del' is not a method that can be called on a dictionary object.
