Short Answer

Expert verified

```python stuff = {1 : 'aaa', 2 : 'bbb', 3 : 'ccc'} for k in stuff: print(k) ``` Answer: The given Python code will display the following output when executed: ``` 1 2 3 ```

Step by step solution

Understanding the Dictionary

In this code, we have a dictionary called "stuff" which has 3 key-value pairs: - Key 1 is mapped to the value 'aaa' - Key 2 is mapped to the value 'bbb' - Key 3 is mapped to the value 'ccc' The dictionary looks like this: stuff = {1 : 'aaa', 2 : 'bbb', 3 : 'ccc'}

Analyzing the For Loop

The given for loop is: for k in stuff: print(k) This loop iterates over the keys of the "stuff" dictionary. In each iteration, the variable 'k' takes on the value of the current key from the dictionary.

Iterating Through the Dictionary Keys

Now let's break down the execution of the loop iteration by iteration: 1. In the first iteration, k = 1 (which is the first key in the dictionary). The code will print the value of 'k', which is 1 2. In the second iteration, k = 2 (which is the second key in the dictionary). The code will print the value of 'k', which is 2 3. In the third iteration, k = 3 (which is the third key in the dictionary). The code will print the value of 'k', which is 3

Final Output

After executing the loop for all iterations, the final output that the code will display is: 1 2 3 These numbers represent the keys of the dictionary items.
