6.2 循环结构——while循环
Python的while循环的一般形式:
while 判断条件:
statements
注意:
1、和if语句一样,要注意冒号和缩进。
2、在Python中没有do..while循环。
Python循环结构——while循环举例
n = 100
sum = 0
counter = 1
while counter <= n:
sum = sum + counter
counter += 1
print("Sum of 1 until %d is %d" %(n,sum))
运行结果:
Sum of 1 until 100 is 5050
Java循环结构——while循环举例
public class Test3 {
public static void main(String[] args) {
int n = 100;
int sum = 0;
int counter = 1;
while(counter <= n){
sum = sum + counter;
counter += 1;
}
System.out.printf("Sum of 1 until %d is %d",n,sum);
}
}
运行结果:
Sum of 1 until 100 is 5050
