如何在相同 class 的另一个 function 中使用 function 的值

Question

class test():
    def abc():
        a = 5;
        b = 6;
        c = 7;
        return a,b,c
    def defg():
        print('inside defg second function')
        a,b,c = abc()
        return a,b,c

when I try to access it a = test(),a.abc()

TypeError: abc() takes 0 positional arguments but 1 was given

Answer 1

class Test():
    def abc(self):
        a = 5
        b = 6
        c = 7
        return a,b,c
    def defg(self):
        print('inside defg second function')
        a,b,c = self.abc()
        return a,b,c

c = Test()
c.defg()

First of all, all class methods must have self first parameter. Second, you need to use self. in one method if you want to call another method of your object. And finally, it is better to call your classes from capital letter.

Otherwise you cane use static methods in your class if your code don't work with instance variables:

class Test():
    @staticmethod
    def abc():
        a = 5
        b = 6
        c = 7
        return a,b,c
    @staticmethod
    def defg():
        print('inside defg second function')
        a,b,c = Test.abc()
        return a,b,c

c = Test()
c.defg()
