Contributed by StemPy LabTry it on paper first. A hint, the key idea and the worked solution are here when you need them.
Print a rectangle of stars with 4 rows and 7 columns. Write it two ways: with one loop and one multiplication, and with two loops.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Plan. One row is "*" * 7. Repeat it 4 times.
One loop.
Two loops. The inner loop prints one star at a time, with end="", and the plain print() starts a new line.
Check. Both versions show the same four lines of seven stars. The inner body runs 4 times 7, which is 28 times.
Answer: The two programs above. The first is shorter, and the second shows how nested loops work.
