Today, I will talk to you about how to use continue and break statements in Python. Many people may not know much about it. In order to make you understand better, the editor has summarized the following content for you. I hope you can get something according to this article.

1. Continue

First look at continue,Enter loop, the loop starts, and then the test condition of the loop, if it is false, then directly jump out of the loop; if it is true, go to continue, determine whether the continue is true or false, if it is true, the loop returns to the test condition at the beginning, jump out of the current loop step, continue to the next loop, if false, the loop continues to execute the remaining statements.

2.break statement

Enter loop, the test condition under which the loop starts and the loop starts. If it is false, the loop ends; if it is true, it goes to the break statement to determine whether the break statement is true or false; if it is true, the loop ends. If false, continue to execute the statement below the loop.

If you don't understand the picture, it doesn't matter. Take a look at some chestnuts and you'll understand. First look at the code, and then you can guess the result first, and finally look at the following output.

For i in range (10):

If I = = 4 or I = 7:

Continue

Print i

Print "- * -" * 10

Print

For i in range (10):

If I = = 4 or I = 7:

Break

Print i

Print "- * -" * 10

Print

For val in "machine learning":

If val = "I":

Continue

Print val

Print "- * -" * 10

Print

For val in "machine learning":

If val = "I":

Break

Print val

Print "- * -" * 10

Print

Val1 = 10

While val1 > 0:

Val1-= 1

If val1 = = 4 or val1 = = 7:

Continue

Print val1

Print "- * -" * 10

Print

Val2 = 10

While val2 > 0:

Val2-= 1

If val2 = = 4 or val2 = = 7:

Break

Print val2
