Today, the editor brings the Getting Started with Python，welcome to visit!一、if语句 if语句表如果，如果满足某某条件，则执行后面得代码。格式为“ if 条件: ”。需要注意的是，满足条件后执行的代码是if语句下面缩进的代码，没有缩进的代码不在if语句的体系内，无论满不满足都会执行。if statement table I...
1、基础语法 在Python中，if语句的基本语法是：if condition:statement(s)如果条件condition为真，则执行if语句后面缩进的语句块。例如:if x <0:pass 如果x小于0，则执行空语句pass。2、多重条件 if语句可以与elif和else语句一起使用，实现多重条件判断。例如：if x<0:print('x是负数')elif x==0:print('...
