How many asterisks will be printed when the following code executes?for x in [0, 1, 2, 3]:    for y in [0, 1, 2, 3, 4]:        print('*')

The code provided is a nested loop, which means it's a loop within another loop. Here's how it works:

1. The outer loop (for x in [0, 1, 2, 3]:) will iterate 4 times, because it has 4 elements in the list (0, 1, 2, 3).

2. For each iteration of the outer loop, the inner loop (for y in [0, 1, 2, 3, 4]:) will iterate 5 times, because it has 5 elements in the list (0, 1, 2, 3, 4).

3. Each time the inner loop iterates, it prints an asterisk (print('*')).

So, to find the total number of asterisks printed, you multiply the number of iterations of the outer loop by the number of iterations of the inner loop.

4 (outer loop) * 5 (inner loop) = 20

So, 20 asterisks will be printed when the code executes.
