Recursionerror: Maximum Recursion Depth Exceeded While Calling A Python Object(algorithmic Change Required)

I am learning about Class Inheritance and overriding methods in python. To implement my learning, I wrote this code to let me better understand how Inheritance and Overriding works

Solution 1:

This line return self.random_digits() and this line return self.unique_id() are infinite recursive loops.

I assume what you intended to return was last_two_digits and id.

When you return a function call, that function has to execute to return the result of its call. Since you are calling the function you are executing it continues calling itself forever.

Corrected code

# Increasing Recursion Limitimport sys  
sys.setrecursionlimit(10000)


import random
# Parent ClassclassUnique_id_creator:  
    def__init__(self, birthdate, birthmonth, birthyear):  
        self.date = birthdate  
        self.month = birthmonth  
        self.year = birthyear  

    defrandom_digits(self):
        last_two_digits = random.randrange(10, 99)
        # convert to a string since you are concatenating the resultreturnstr(last_two_digits)

    defunique_id(self):
        id = int(self.date + self.month + self.year + self.random_digits())
        returnid# Child ClassclassUnique_id_distributer(Unique_id_creator):  
    def__init__(self, name, birthdate, birthmonth, birthyear):  
        Unique_id_creator.__init__(self, birthdate, birthmonth, birthyear)  
        self.name = name  

    defunique_id(self):
        id = Unique_id_creator.unique_id(self)
        return"Dear "+ str(self.name) + ", Your Unique Id is: "+ str(id)

citizen1 = Unique_id_distributer("hasan", "01", "11", "2000")  
print(citizen1.unique_id())

Additionally, you can eliminate the full call of your parent class by using super().

Child class example

# Child ClassclassUnique_id_distributer(Unique_id_creator):  
    def__init__(self, name, birthdate, birthmonth, birthyear):  
        super().__init__(birthdate, birthmonth, birthyear)  
        self.name = name  

    defunique_id(self):
        id = super().unique_id()
        return"Dear "+ str(self.name) + ", Your Unique Id is: "+ str(id)
