Loops with Variables — Part 19

Steps

1. 1Look at the 'for' line. It says: repeat the indented code a certain number of times. range(${Math.min(3 + Math.floor(n / 2), 8)}) means ${Math.min(3 + Math.floor(n / 2), 8)} times.
2. 2The indented line (print) runs once for each number in range(). So it would print Step 1, Step 2, Step 3... up to Step ${Math.min(3 + Math.floor(n / 2), 8)}.
3. 3Without a loop, you'd need to write ${Math.min(3 + Math.floor(n / 2), 8)} separate print() lines! Loops save you from repeating yourself.
4. 4The 'i' variable counts which round we're on (starting from 0). That's why we write i + 1 to show Step 1 instead of Step 0.

Key Terms

Loop

A way to repeat the same steps multiple times without writing them again and again.

range()

Gives you a sequence of numbers (e.g. 0, 1, 2) so the loop knows how many times to run.

Repeat

To do the same thing more than once. Loops help us repeat.
