我能否以某种方式合并这些类，这样我就不必一次又一次地编写它，并且我的 python 代码不会变得多余

# I AM CREATING A BIKE RENTAL SYSTEM USING OOP IN PYTHON AND SOMEHOW I SEE MYSELF REPEATING SAME CONTENTS IN METHODS, CAN I SOMEHOW WRITE THIS IN BETTER FORMAT WHICH ISNT REDUNDANT? (I AM NEW TO OOP)

class BikeRental:

    def __init__(self, stock=0):
        #creating instances of bike rental shop
        self.stock = stock

    def displayStock(self):

        print(f'We currently have {self.stock} bikes available for rent')
        return self.stock

        #rents bike on hourly basis
        if input < 0:
            print('Number of bikes should be positive!')
            return None

        elif input > self.stock:

            print('you will be charged 5$ per bike per hour.')

Answer 1

I'm assuming you are asking about repeating the function, not the class. If so, something like this might be helpful, with the idea being to have different functions call the one BikeOnBasis function with a varying parameter basis. Also see polymorphism for info on doing this type of thing in more structured ways.
