Next, decrease the value of offset by 1. These instructions (loop) is repeated until a condition is met. Here’s what’s happening in this example: n is initially 5.The expression in the while statement header on line 2 is n > 0, which is true, so the loop body executes.Inside the loop body on line 3, n is decremented by 1 to 4, and then printed. So, the first time through, it counts the odds and evens for that run, until num gets to 100. Does or condition work in a while loop in python?
