def start_engine(self): print(f"{self.make} {self.model} engine started.") def stop_engine(self): print(f"{self.make} {self.model} engine stopped.") 在这个例子中 ,Car类有三个属性:make(制造商)、model(型号)和year(年份),以及两个方法:start_engine和stop_engine。类定义完成后,我们可以通...

这个例子还介绍了in关键字。它测试序列中是否包含某个确定的值 默认值在函数定义作用域被解析,如下所示: 输出为5,值得思考? 重要警告: 默认值只被赋值一次。这使得当默认值是可变对象时会有所不同,比如列表,字典或者大多数类的示例。例如,下面的函数在后续调用过程中会累积(前面)传给它的参数: ...
