whileexpression:whileexpression: statement(s) statement(s) 关于循环嵌套的最后一点是,您可以将任何类型的循环放入任何其他类型的循环内。例如 for 循环可以在 while 循环中,反之亦然。 示例 以下程序使用嵌套 for 循环来显示 1-10 的乘法表。 #!/usr/bin/python3importsysforiinrange(1,11):forjinrange(1,...
Thebreak statementis used inside the loop to exit out of the loop. If thebreak statementis used inside a nested loop (loop inside another loop), it willterminate the innermost loop. In the following example, we have two loops. The outerforloop iterates the first four numbers using therange...
Python编程语言中嵌套的WHILE LOOP语句的语法如下所示:- while expression: while expression: statement(s) statement(s) 1. 2. 3. 4. 关于循环嵌套的最后一个注意事项是,您可以将任何类型的循环放在任何其他类型的循环中。如,for循环可以在while循环中,反之亦然。 nested loops - 示例 下面的程序使用嵌套的FOR...
Nested If-Else Blocks In Python, we can also havenested if-elseblocks. For example, the following code checks the number in the if block. If it is greater than zero, it prints the message. If the number is less than zero, it prints the message as a negative number. Otherwise, it pr...
Python while 循环嵌套语法:while expression: while expression: statement(s) statement(s)你可以在循环体内嵌入其他的循环体,如在while循环中可以嵌入for循环,反之,你可以在for循环中嵌入while循环。实例:以下实例使用了嵌套循环输出2~100之间的素数:实例 #!/usr/bin/python # -*- coding: UTF-8 -*- i = ...

If do_stuff is more than one line, it should be put on the next line and indented. The 'condition' is evaluated before each iteration of the loop, and 'do_stuff' is executed so long as 'condition' is true.While Loops in Python A while statement in python sets aside a block of ...
