Question

What is the correct syntax for adding a key called "variety" to the `fruit_info` dictionary that has a value of "Red Delicious"?

Answer 1

To add a new key 'variety' with the value 'Red Delicious' to a dictionary in Python, the syntax is fruit_info['variety'] = 'Red Delicious'. If 'variety' doesn't exist, it gets added; if it does, its value is updated.

Step-by-step explanation:

The student wishes to know the correct syntax for adding a new key-value pair to a dictionary in Python. If we have a dictionary called fruit_info and want to add a new key variety with the value Red Delicious, we can do so using the following syntax:

fruit_info['variety'] = 'Red Delicious'

This line of code will update the fruit_info dictionary by setting the variety key to the value Red Delicious. If the key 'variety' already exists, its value will be updated to 'Red Delicious'; if it does not exist, the 'variety' key will be added with the new value.
