While loop in python

 The basic structure of a while loop looks like this:

python
while (condition):
    # code to be executed

Here, "condition" is an expression that returns a Boolean value (either True or False). The code within the loop will continue to be executed as long as the condition is True. Once the condition becomes False, the loop will stop and the program will continue with the next statement after the loop.

It's important to make sure that the condition eventually becomes False, otherwise the loop will run forever, causing an infinite loop.

Here's an example of using a while loop to print the numbers from 1 to 5:

python
count = 1

while (count <= 5):
    print(count)
    count += 1

This will output the following:

1
2
3
4
5

While loops are useful when you want to repeat a set of actions while a certain condition remains true, and they are often used in conjunction with conditional statements (e.g., if-else) to control the flow of a program.
