Question

What will the following code display? stuff = {1 : 'aaa', 2 : 'bbb', 3 : 'ccc'} for k in stuff: print(k)

Short answer

```python stuff = {1: 'aaa', 2: 'bbb', 3: 'ccc'} for k in stuff: print(k) ``` Answer: The output will be the keys of the 'stuff' dictionary, which are the integers 1, 2, and 3.

Step-by-step solution

Understand the 'stuff' dictionary

The 'stuff' dictionary contains three keys and their corresponding values: 1 with 'aaa', 2 with 'bbb', and 3 with 'ccc'. The keys are integers and the values are strings. The dictionary looks like this: stuff = {1: 'aaa', 2: 'bbb', 3: 'ccc'}

Analyze the for loop

The for loop iterates over the keys of the 'stuff' dictionary. The variable 'k' takes the value of each key in the dictionary during each iteration of the loop.

Understand the print statement

Inside the for loop, we have a print statement that prints the value of 'k'. This means that we will see the keys of the 'stuff' dictionary being printed, one per line.

Combine information to find the output

Based on the analysis above, the code will display the keys of the 'stuff' dictionary, which are 1, 2, and 3 in this case. The output will look like this: 1 2 3
