how to return the class function in python?

Question

I called the other function from the first function. when I return the first function, I am getting python None on the screen.

class test():

    def test1(self, userinput):

        return self.test2(userinput)

    def test2(self, urls):

        string = "this is " + urls
        self.test3(string)

    def test3(self, sentence):
        return sentence


if __name__ == "__main__":

    objectt = test()
    seek = "concept of my functions"
    print(objectt.test1(seek))

The test2 function doesn't return anything, so it returns None by default — moebius

Please learn about rubber duck debugging. Attempting to explain the code to a "rubber duck" (or roommate, friend or other suitable substitute) often helps. — Some programmer dude

In test2, you call test3.

test3 returns 'this is concept of my function' to test2. Then, test2 returns nothing to test1 - so, as all functions that don't return anything specific, it returns None, which in turn is returned by test1.

You have to return the output of test3 at the end test2: class test():

class test:
    def test1(self, userinput):

        return self.test2(userinput)

    def test2(self, urls):

        string = "this is " + urls
        return self.test3(string)

    def test3(self, sentence):
        return sentence


objectt = test()
seek = "concept of my functions"
print(objectt.test1(seek))

# this is concept of my functions
