WebPython Loops Python has two primitive loop commands: while loops for loops The … WebA for loop is usually used when the number of iterations is known. For example, // This loop is iterated 5 times for (int i = 1; i <=5; ++i) { // body of the loop } Here, we know that the for-loop will be executed 5 times. However, while and do...while loops are usually used when the number of iterations is unknown.

The following while loop iterates as long as n is less than three. let n = 0; let x = 0; while (n < 3) { n++; x += n; } Each iteration, the loop increments n and adds it to x . Therefore, x and n take on the following values: After the first pass: n = 1 and x = 1. After the second pass: n = 2 and x = 3.
