python 循环区分(while循环和for循环)

人工智能 Python


适用性
while循环,适用于未知循环次数的循环;
for循环,适用于已知循环次数的循环;

详细解释
1、【循环次数基本可知】for适合遍历数据,数据遍历没有了就结束;
2、【循环次数基本不可知,通过判断条件的反条件来结束循环】while循环前,需要判断条件,相对适合逻辑比较复杂的循环;

备注:while循环和for循环,两者之间部分是可以切换的!!!

说明
1、本人第一次写CSDN博客,希望大家支持!
2、本人6年测试行业经验,3年黑盒测试经验,3年测试开发经验,曾任职国内大型人工智能上市公司,精通性能测试,自动化测试,接口测试,人工智能AI语音测试;
3、如下是本人内部沟通群,欢迎对于测试志同道合的人加入,大家一起沟通交流!
