How do you create a while loop in Python?

To create a while loop in Python, the correct approach involves using the while keyword followed by a condition. This structure allows the loop to execute a block of code repeatedly as long as the specified condition evaluates to true. The syntax typically looks like this:

while condition:

# code to execute

When the program reaches this loop, it checks the condition. If the condition is true, the code within the loop is executed. After executing the loop's code, the condition is checked again. This repeats until the condition evaluates to false, at which point the loop terminates and the program continues with the code that follows the loop.

This construction is particularly useful when the number of iterations is not predetermined, allowing for dynamic looping based on the condition being evaluated during runtime. The `while` loop provides a flexible way to control program flow based on specific criteria, making it a fundamental component of programming in Python.
