How do you create a while loop in Python?

To create a while loop in Python, you use the while keyword followed by a condition. The while loop repeatedly executes a block of code as long as the specified condition evaluates to True. This enables the program to perform repetitive tasks until a certain condition is met, which can be very useful for scenarios like processing user input, iterating over data that changes dynamically, or running an operation until a particular state is reached.

For example, if you want to print numbers from 1 to 5, you could set up a while loop like this:

number = 1

while number <= 5:

print(number)

number += 1

In this example, the loop will continue to execute until the variable number exceeds 5, showcasing how the loop leverages the condition provided.

Other options presented do not align with the syntax and concepts used in Python for creating loops. For instance, the do keyword and repeat keyword are not part of Python's syntax for loop structures, and the for keyword is used to iterate over a predefined iterable rather than to create a condition-based loop like the while loop.
