Question

Review the code below. What is the correct syntax for changing the price to 1.5?

1) fruit_info['price'] = 1.5
2) fruit_info.price = 1.5
3) fruit_info.price == 1.5
4) fruit_info.price = '1.5'

Answer 1

The correct syntax to change the price to 1.5 in the code provided is fruit_info['price'] = 1.5, which uses the correct dictionary assignment syntax in Python.

Step-by-step explanation:

To change the price to 1.5 in the given code, the correct syntax is fruit_info['price'] = 1.5. This is because in Python, dictionaries are accessed using square brackets with the key name to assign a new value to a key. Thus, option 1) is correct.

Option 2) fruit_info.price = 1.5 is incorrect because it assumes fruit_info is an object with an attribute price, which is not the case with a dictionary. Option 3) fruit_info.price == 1.5 is a comparison, not an assignment. Option 4) fruit_info.price = '1.5' not only uses incorrect dot notation, but it also assigns a string rather than a floating-point number, which would be incorrect if we want the price to be a numerical value.
