1. What is printed on the second line? ``

python
def row(width, widest):
    indent = (widest - width) // 2
    return " " * indent + "*" * width


def main():
    widest = 3
    stem_height = 2
    for w in range(1, widest + 1, 2):
        print(row(w, widest))
    for _ in range(stem_height):
        print(row(1, widest))


main()

``

* **** *

2. What is printed on the third line? ``

python
def row(width, widest):
    indent = (widest - width) // 2
    return " " * indent + "*" * width


def main():
    size = 4
    middle = size // 2
    for r in range(size):
        width = size if r == middle else 1
        print(row(width, size))


main()

``

**** * *****

3. In the hourglass program from the lesson, why does the second loop start at w = 3 and not at w = 1?

Width 1 has an indent of 2, which the second loop does not allow.The first loop already printed the single-star row, so starting at 1 would print that star twice.The widest row must be printed first in the second loop.Python's * operator cannot repeat a string just once.

4. In an hourglass with widest = 7, a row has width 3. How many spaces come before its stars?

1342

5. Which operator repeats a string, so that " " * 2 gives two spaces? Give the symbol only.
