Python Process Control statements

If statement

If...else statements

If...elif...else statements

Nested IF statements

You can add an if ... else statement to another if ... else statement, which is called nested. elif. elif.

For loop

While < judging conditions:

< cycle body >

For ... else

The For loop can also have an optional else block, and if the loop executes normally (that is, it is interrupted by a break jump), the else part is executed.

Note: The break statement can be used to jump out of a for loop, in which case the else part is ignored.

While loop

While < judging conditions:

< cycle body >

While ... else

As with the For loop, you can also have an optional else block in the while loop.

If the judgment condition in the while loop is False, the else part is executed.

Note: While loops can be terminated with the break statement, in which case the else part is ignored.
