类(Class): 定义:类是一个蓝图或模板,用于创建具有相同属性和方法的对象。它定义了对象的结构和行为。 创建新类:通过定义一个类,你创建了一个新的对象类型(type of object)。这意味着你可以创建该类的多个实例,每个实例都是类的一个具体化,拥有类定义的属性(attributes)和方法(methods)。
class:用于定义类,实现面向对象编程。 def:用于定义函数。 if:条件语句的关键字,用于进行条件判断。 elif:在if...else结构中用作多条件分支判断,相当于else if。 else:与if或for/while循环一起使用,表示当条件不满足时执行的代码块。 try:开始一个异常处理结构。
