While in While Python

Python has a powerful control structure for looping, called "while". The while loop allows you to repeat a set of instructions over and over again until a certain condition is met. It is a very versatile looping tool and can be used in many different ways.

The most basic form of a while loop is the following:

while condition:
    statement(s)

This while loop will execute the statement(s) as long as the condition is true. The condition is evaluated at the beginning of each loop. If it is true, the statement(s) are executed, and then the condition is evaluated again.

For example, let's say we want to print out the numbers from 1 to 10. We can use a while loop to accomplish this:

num = 1
while num <= 10:
    print(num)
    num += 1

This loop will execute 10 times, starting with 1 and ending with 10. On each iteration, the value of num is printed out and then incremented by 1. Once the value of num reaches 11, the condition is no longer true and the loop exits.

It's also possible to use a while loop within another while loop. This is often referred to as a "nested while loop". Let's look at an example of this:

num1 = 1
while num1 <= 10:
    num2 = 1
    while num2 <= 10:
        print(num1 * num2)
        num2 += 1
    num1 += 1

In this example, we have a nested while loop that prints out the product of the two numbers, num1 and num2. The outer loop runs 10 times, starting with 1 and ending with 10. On each iteration, the inner loop runs 10 times, starting with 1 and ending with 10. The product of the two numbers is printed out on each iteration, and then num2 is incremented by 1. Once num2 reaches 11, the inner loop exits and num1 is incremented by 1.

Using a while loop within a while loop is a powerful way to perform complex tasks with minimal code. It can be used to iterate over multi-dimensional data structures, perform complex calculations, and more.
