1. With three rows, what does this call print? ``

python
def row_of(index, num_rows):
    cycle = 2 * (num_rows - 1)
    position = index % cycle
    if position < num_rows:
        return position
    return cycle - position

print(row_of(5, 3))

``

0213

2. What does this print? ``

python
print(f"[{12:4d}][{12:<4d}]")

``

[ 12][12 ][12][12][12 ][ 12][ 12][ 12]

3. In the bouncing-star program (the first zigzag example), when the marker is on the top row, what value does direction get set to?

Type your answer.

4. In the f-string f"{price:10.2f}", how many digits come after the decimal point?

Type your answer.

5. In the look-ahead version of the bounce (Example 2), which test turns the direction around?

direction == 1, checked before the movenext_row < 0 or next_row >= rows, which checks whether the next row leaves the boardrow == 0, which only checks the top edgestep < steps, which decides when the loop stops
