The answer is D. The program prints:
buzz
This answer was checked by running the program for real.
Why?
A dictionary stores pairs: a key and its value. sounds["bee"] looks up the key ‘bee’ and gives back its value.
Trace table
A trace table follows the program step by step. Here’s this one:
| key | value |
|---|---|
| owl | hoot |
| frog | ribbit |
| bee | buzz |
| cat | meow |
The code again
sounds = {
"owl": "hoot",
"frog": "ribbit",
"bee": "buzz",
"cat": "meow",
}
print(sounds["bee"])Try it: change one number in the program and predict the new output before you run it.
