Python loop statement
This chapter will introduce you to Python's looping statements, which are normally executed in order.
The programming language provides a variety of control structures that allow for more complex execution paths.
The loop statement allows us to execute a statement or group of statements multiple times. The following is the general form of loop statements in most programming languages:
Python provides for loops and while loops (no do..while loops in Python):
| Cycle Type | Description |
|---|---|
| while loop | in the given judgment condition is The loop body is executed when true, otherwise the loop body is exited. |
| for loop | repeating statements |
| nested loop | you can loop inside the while Nested for loop |
Cycle Control Statement
The loop control statement can change the order in which statements are executed. Python supports the following loop control statements:
| Control Statement | Description |
|---|---|
| break statement | terminates during statement block execution Loop and jump out of the loop |
| continue statement | terminates the current state during statement block execution Loop, jump out of the loop and execute the next loop. |
| pass statement | pass is an empty statement, for Maintain the integrity of the program structure. |
