在python中从一个类继承一个函数到另一个类？

Question

我有一个类调用两个函数和两个实例方法。你知道吗

    class MyClass(object):
        def df1(self):
            raw_data = {'preTestScore': [4, 24, '', 2, 3],'postTestScore': [25, 94, 57, 62, 70]}
            df1 = pd.DataFrame(raw_data, columns = ['preTestScore', 'postTestScore'])
            return df1

        def df2(self):
            raw_data = {'preTestScore': [14, 4, 15, 12, 13],'postTestScore': ['', 4, 7, 2, 7]}
            df2 = pd.DataFrame(raw_data, columns = ['preTestScore', 'postTestScore'])
            return df2

        def df1_and_df2(self):
            return (self.df1(), self.df2())

以及如何从另一个类继承这两个df

  class MySecond():
       #call df1 and df2 from MyClass
       #work on from those two dfs

Answer 1

在课堂上你可以

obj = MyClass()
obj.dfl()
obj.df2()

您还可以让MySecond继承MyClass

class MySecond(MyClass):
   #code
