Python——》导包、继承、抛异常

1、继承

"""继承"""

class Father(object):

    def father_study(self):
        """
        学习羽毛球
        :return:
        """
        sport = '学习羽毛球'
        return sport

class Child(Father):
    def child_study(self):
        """
        继承父亲的学习方向
        :return:
        """
        return super().father_study()


child = Child()
print(child.child_study())

运行结果：

D:\Study\pythonProject\venv\Scripts\python.exe D:/Study/pythonProject/PythonBasic/Test1203.py
学习羽毛球

Process finished with exit code 0

2、导包继承

父类：

"""继承"""

class Father(object):

    def father_study(self):
        """
        学习羽毛球
        :return:
        """
        sport = '学习羽毛球'
        return sport

子类继承父类：

"""导包、继承"""
from PythonBasic.Test1203 import Father


class Child(Father):
    def child_study(self):
        """
        继承父亲的学习方向
        :return:
        """
        return super().father_study()


child = Child()
print(child.child_study())

运行结果：

D:\Study\pythonProject\venv\Scripts\python.exe D:/Study/pythonProject/PythonBasic/Test1204.py
学习羽毛球

Process finished with exit code 0

3、抛异常

"""抛异常"""
try:
    print('需要执行的代码')
except:
    print('如果存在异常，执行本代码')
else:
    print('如果无异常，执行本代码')
finally:
    print('无论有没有异常，均执行代码')
