Bất cứ khi nào tôi chạy mã của mình, tôi nhận được: nameerror: name 'object_oriented_programming' không được xác định

Show

Làm cách nào để xác định tên Object_oriented_programming?

Code:

class Object_Oriented_Programming:
    
    class Inheritance():
        def __init__(self, name, age):
            self.name = name
            self.age = age

        class SchoolMember():
            '''Represents any school member.'''

            def __init__(self, name, age):
                self.name = name
                self.age = age
                print('(Initialized SchoolMember: {})'.format(self.name))

            def tell(self):
                '''Tell my details.'''
                print('Name:"{}" Age:"{}"'.format(
                    self.name, self.age), end=" ")

        class Teacher(SchoolMember):
            '''Represents a teacher.'''

            def __init__(self, name, age, salary):
                Object_Oriented_Programming.Inheritance.SchoolMember.__init__(
                    self, name, age)
                self.salary = salary
                print('(Initialized Teacher: {})'.format(self.name))

            def tell(self):
                Object_Oriented_Programming.Inheritance.SchoolMember.tell(self)
                print('Salary: "{:d}"'.format(self.salary))

Theo như tôi quan tâm về mã, tôi đã chạy nó trên thiết bị đầu cuối và không có vấn đề gì, nó được thực hiện đơn giản và không có gì hiển thị vì không có gì được in.

Bây giờ, nếu bạn thực sự muốn biết cách xác định một đối tượng trong OOPS trong Python, thì đây là cách để làm điều đó:

  1. Đầu tiên thay vì tạo một lớp bên trong một lớp, bạn chỉ nên tạo một lớp và sau đó viết phương thức 
            class train:
    def __init__(self, name, fare, seats, code):
        self.name = name
        self.fare = fare
        self.seats = seats
        self.code = code

    def train_Status(self):
        print(f"The name of the train is {self.name}")
        print(f"The seats is {self. seats}")

    def fare_Info(self):
        print(f"The fare is {self. fare}")

    def code_Info(self):
        print(f"The code is {self. code}")

    def tickets_Info(self):
        if(self.seats > 0):
            print(
                f"The seats are available for you...\nYour seat number is {self.seats}")
            self.seats = self.seats - 1
        elif(self.seats == 0):
            print("The seats are not available for you...")
        else:
            print("The server isnt updated yet. \nPlease try again later.")

    @staticmethod
    def greeting():
        print("Welcome to Rajdhani express!!")


Inter = train("Inter Express", 180, 12, 239340)
Inter.greeting()
Inter.fare_Info()
Inter.train_Status()
Inter.tickets_Info()
Inter.train_Status()
Inter.code_Info()
    8 bao gồm tất cả những thứ như tên hoặc tuổi.
  2. Khi nào với điều này, sau đó bạn có thể tạo một biến mới ở cuối và đặt nó = tên lớp (tên, tuổi). Ví dụ, tôi đã đính kèm một IMG để hiển thị cho bạn một đoạn mã.

Biến Python là các container lưu trữ giá trị. Python không phải là người đánh máy thống trị. Chúng tôi không cần phải khai báo các biến trước khi sử dụng chúng hoặc khai báo loại của chúng. Một biến được tạo ngay khi chúng ta gán một giá trị cho nó. Một biến Python là một tên được đặt cho một vị trí bộ nhớ. Nó là đơn vị lưu trữ cơ bản trong một chương trình.

Ví dụ về các biến Python

Python3

        class train:
    def __init__(self, name, fare, seats, code):
        self.name = name
        self.fare = fare
        self.seats = seats
        self.code = code

    def train_Status(self):
        print(f"The name of the train is {self.name}")
        print(f"The seats is {self. seats}")

    def fare_Info(self):
        print(f"The fare is {self. fare}")

    def code_Info(self):
        print(f"The code is {self. code}")

    def tickets_Info(self):
        if(self.seats > 0):
            print(
                f"The seats are available for you...\nYour seat number is {self.seats}")
            self.seats = self.seats - 1
        elif(self.seats == 0):
            print("The seats are not available for you...")
        else:
            print("The server isnt updated yet. \nPlease try again later.")

    @staticmethod
    def greeting():
        print("Welcome to Rajdhani express!!")


Inter = train("Inter Express", 180, 12, 239340)
Inter.greeting()
Inter.fare_Info()
Inter.train_Status()
Inter.tickets_Info()
Inter.train_Status()
Inter.code_Info()

Notes:

  • Giá trị được lưu trữ trong một biến có thể được thay đổi trong quá trình thực hiện chương trình.
  • Một biến Python chỉ là một tên được đặt cho vị trí bộ nhớ, tất cả các hoạt động được thực hiện trên các hiệu ứng biến vị trí bộ nhớ đó.

Các quy tắc để tạo các biến trong Python

  • Một tên biến phải bắt đầu bằng một chữ cái hoặc ký tự dấu gạch dưới.
  • Một tên biến không thể bắt đầu với một số.
  • Một tên biến chỉ có thể chứa các ký tự alpha-numeric và nhấn mạnh (A-Z, 0-9 và _).
  • Tên biến là nhạy cảm trường hợp (tên, tên và tên là ba biến khác nhau).
  • Các từ dành riêng (từ khóa) không thể được sử dụng đặt tên biến.

Hãy cùng xem các biến biến đơn giản:

  • Từ khóa toàn cầu trong Python

Example:

Từ khóa toàn cầu là một từ khóa cho phép người dùng sửa đổi một biến bên ngoài phạm vi hiện tại. Nó được sử dụng để tạo các biến toàn cầu từ một phạm vi không toàn cầu, tức là bên trong một hàm. Từ khóa toàn cầu chỉ được sử dụng bên trong một chức năng khi chúng tôi muốn thực hiện các bài tập hoặc khi chúng tôi muốn thay đổi một biến. Toàn cầu là không cần thiết để in và truy cập.

Quy tắc từ khóa toàn cầu:

Nếu một biến được gán một giá trị ở bất cứ đâu trong cơ thể chức năng, thì nó được coi là địa phương trừ khi được tuyên bố rõ ràng là toàn cầu.

Các biến chỉ được tham chiếu bên trong một hàm là toàn cầu ngầm.

Chúng tôi sử dụng từ khóa toàn cầu để sử dụng một biến toàn cầu bên trong một hàm.

Làm thế nào để bạn xác định tên trong Python 3?

Dưới đây là các quy tắc đơn giản để xác định một chức năng trong Python. Các khối chức năng bắt đầu với từ khóa def theo sau là tên hàm và dấu ngoặc đơn (()). Bất kỳ tham số đầu vào hoặc đối số nên được đặt trong các dấu ngoặc đơn này. Bạn cũng có thể xác định các tham số bên trong các dấu ngoặc đơn này.Function blocks begin with the keyword def followed by the function name and parentheses ( ( ) ). Any input parameters or arguments should be placed within these parentheses. You can also define parameters inside these parentheses.

Làm cách nào để xác định một biến trong Python?

Python không có lệnh để khai báo một biến.Một biến được tạo ngay khi bạn chỉ định một giá trị cho nó.. A variable is created the moment you first assign a value to it.

Làm thế nào để bạn đặt một biến một tên?

Các quy tắc cho các biến đặt tên:..
Tất cả các tên biến phải bắt đầu bằng một chữ cái của bảng chữ cái hoặc một.gạch dưới (_).....
Sau chữ cái đầu tiên, tên biến cũng có thể chứa các chữ cái và số.....
Các ký tự chữ hoa khác biệt với các ký tự thường.....
Bạn không thể sử dụng từ khóa C ++ (từ dành riêng) làm tên biến ..

Tên có phải là một biến trong Python không?

Tên biến là nhạy cảm trường hợp (tên, tên và tên là ba biến khác nhau).Các từ dành riêng (từ khóa) không thể được sử dụng đặt tên biến.). The reserved words(keywords) cannot be used naming the variable.
