pycharm提示This inspection detects any methods which may safely be made static.

示例代碼：

class Car(object):
	# 未定義任何類屬性

    def move(self):  # 方法會出現下划線提示This inspection detects any methods which may safely be made static.
        print("---車在移動---")

    def stop(self):
        print("---停車---")

原因是該方法不涉及對該類屬性的操作，編譯器建議聲明為@staticmethod，面向對象思想體現
