Consider the following code segment:
fruit = {"Apple": "Green", "Banana": "Yellow"}
fruit["Apple"] = "Red"
After it executes, what is the value of fruit?

Question

BlackTom AI · Accepted Answer

We are given a Python-like dictionary operation scenario and asked to determine the resulting dictionary after a mutation.
First, the initial dictionary is fruit = {"Apple": "Green", "Banana": "Yellow"} so it starts with two key-value pairs: Apple maps to Green and Banana maps to Yellow.
Next, the statement fruit["Apple"] = "Red" updates the value associated with the key "Apple" from Green to Red. In Python dictionaries, assigning to an existing key overwrites the previous value for that key without changing other keys.
Now evaluate each option:
- Option 1: {"Apple": "Green", "Banana": "Yellow"} shows the Apple value unchanged as Green. This would be true if no assignment occurred, but we did assign a new value to Apple, so this is incorrect.
- Option 2: {"Apple": "Red", "Banana": "Yellow"} reflects Apple updated to Red while Banana remains Yellow, which matches the actual mutation outcome.
- Option 3: {"Apple": "Green", "Banana": "Yellow", "Apple": "Red"} is inconsistent because a dictionary cannot have two separate entries with the same key; the latter assignment overwrites the former, so this structure is invalid in Python and incorrect.
- Option 4: The claim that the dictionary has no value due to a runtime error is incorrect because this code does not produce a runtime error; the operation is valid and simply updates the value.
In summary, the only option that aligns with the mutation described is the one where Apple's value becomes Red while Banana remains Yellow, reflecting the standard behavior of key assignment in dictionaries.
