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

Question

import datetime

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

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

        elif input > self.stock:
            print(f'Sorry we have {self.stock} bikes available right now!')
            return None

        else:
            now = datetime.datetime.now()
            print(f'you have rented {input} bike/bikes on hourly basis today'
                  f'at {now.hour} on {now.date()}')
            print('you will be charged 5$ per bike per hour.')
            print('Have a great and healthy day!')

            self.stock -= input
            return now

    def BikeOnDailyBasis(self, n):

        if n< 0:
            print('Number of bikes should be positive!')
            return None
        elif n >self.stock:
            print(f'Sorry we have {self.stock} bikes available right now!')
        else:
            now = datetime.datetime.now()
            print(f'you have rented {n} bike/bikes on hourly basis today'
                  f'at {now.hour} on {now.date()}')
            print('you will be charged 5$ per bike per hour.')
            print('Have a great and healthy day!')

            self.stock -= n
            return now

Answer 1

我假设您要问的是重复 function，而不是 class。 如果是这样，这样的事情可能会有所帮助，其想法是让不同的函数调用具有不同参数基础的 BikeOnBasis function。 另请参阅多态性以获取有关以更结构化的方式执行此类操作的信息。
