This article mainly introduces "how to use Python loop". In daily operation, I believe many people have doubts about how to use Python loop. The editor consulted all kinds of data and sorted out simple and easy-to-use operation methods. I hope it will be helpful for you to answer the doubts about "how to use Python loop"! Next, please follow the editor to study!

Loops in Python

There are two types of loops built into Python:

For cycle

While cycle

Let's focus on how while creates loops in Python and how they work.

What is the while loop in Python?

The general syntax of the while loop in Python is as follows:

While condition: execute this code in the loop's body

The while loop will run a piece of code when the condition is True. It will continue to execute the required set of code statements until the condition is no longer True.

The while loop always checks the conditions before running.

If the condition is evaluated as True, the loop runs the code inside the loop.

For example, as long as number 7: break

The code will be run at least once, requiring user input.

It is always guaranteed to run at least once, using True, otherwise an infinite loop will be created.

If the user enters the correct password, the loop terminates.

If the user enters the wrong password more than 7 times, the loop exits completely.

This break statement allows you to control the flow of a while loop instead of ending in an infinite loop.

Break immediately terminates the current loop and exits it.

This is how you do while to create a loop-like effect in Python.

The loop is always executed at least once. If the condition is not met, it continues the loop and then terminates when the condition is met.

At this point, the study on "how to use the Python loop" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
