Hy vọng điều này là đủ rõ ràng: class myParent():
def __init__( self ):
self.parentNumber = 5
class Child( myParent ):
def __init__( self ):
self.childNumber = 4
def multiplyNumbers( self ):
print myParent.parentNumber * self.childNumber
p = Child()
p.multiplyNumbers()
Tôi muốn đặt ParentNumber riêng lẻ, và sau đó đạt được số đó thông qua lớp con và trong trường hợp này, hãy sử dụng nó để nhân. Tôi là người mới đến khu vực OOP nên bất kỳ gợi ý chung nào về thừa kế cũng được chào đón! Thông tin thêm: Tôi đang thiết kế một giải pháp quản lý dự án cho các dự án dựa trên VFX và đang chơi với các lớp học và kế thừa để xem họ có thể giúp tôi như thế nào. I'm designing a project management solution for vfx-based projects, and am playing with classes and inheritance to see how they can help me the most. Ngay bây giờ, tôi đã có một lớp hàng đầu, dự án và một lớp có nguồn gốc, bắn. Bắn có một biến tự.length với độ dài của ảnh chụp cụ thể. Nó cũng có một phương thức getLpminseconds () sử dụng self.length cùng với dự án.fps để xác định độ dài tính bằng giây. Project có một phương thức setFps () trong đó FPS được đặt sau một phiên bản của lớp được tạo. Tôi đã quen với các biến được đặt trước với bản thân. và đã không thử nghiệm nhiều với các lớp sử dụng các biến "toàn cầu" hơn mà không có bản thân. . Nếu tôi tạo ra mọi thứ toàn cầu, không có bản thân. Có lẽ có một cách tốt hơn, gọn gàng hơn,? Edit: Sau khi đọc, Super () có vẻ hơi nguy hiểm, và nhiều hơn tôi cần tôi nghĩ. Tôi chủ yếu có các lớp tự nhiên đơn và thậm chí không chắc chắn làm thế nào để sử dụng phân cấp kim cương .. Có cách nào an toàn hơn để truy cập các biến và phương thức siêu lớp không bao gồm Super () không? Edit: Được rồi, xem điều này có ý nghĩa hay nếu tôi nghĩ về nó sai. Tôi đang xem xét các lớp học và kế thừa như các nhóm và trẻ em. Một đứa trẻ biết đó là cha mẹ và tất cả các giá trị của nó. Một đứa trẻ với cha mẹ khác biết rằng cha mẹ coi trọng. Những gì tôi đang cố gắng thực hiện là có tất cả các bức ảnh được tạo ra là một phần của dự án. Và ngay bây giờ, tôi đang tạo các trường hợp shot () từ trong lớp Project (), thêm các phiên bản vào danh sách các bức ảnh được duy trì trong phiên bản dự án (). i.e. class myParent( object ):
def __init__( self ):
self.parent_id = ''
self.children = []
def createChild( self, name ):
self.children.append( myChild( name ) )
def getChildren( self ):
return self.children
def setParentId( self, id ):
self.parentId = id
class myChild( myParent ):
def __init__( self, id ):
super(myChild, self).__init__()
self.id = id
def getParentId( self ):
return self.parent_id
p = myParent()
p.setParentId( 'parent01' )
p.createChild( 'child01' )
print p.getChildren()[0].getParentId()
Tôi có thể thấy các bước sai trong logic ở đây, nhưng không có cách nào thực sự xung quanh nó .. Có vẻ như mọi đứa trẻ đều nhận được một ví dụ mới của cha mẹ theo cách này, trong đó Parent_id luôn là một chuỗi trống. COE

Lưu ý: Để biết thêm thông tin, hãy tham khảo các lớp và đối tượng Python. For more information, refer to Python Classes and Objects. Truy cập các chức năng của lớp chaKhi một lớp kế thừa từ một lớp khác, nó kế thừa các thuộc tính và phương thức của một lớp khác. Một lớp kế thừa từ một lớp khác được gọi là lớp con và lớp mà lớp con được thừa hưởng được gọi là lớp cha. Nhưng bạn đã bao giờ tự hỏi làm thế nào để truy cập các phương pháp lớp cha mẹ? Điều này thực sự đơn giản, bạn chỉ cần gọi hàm tạo của lớp cha trong hàm tạo của lớp con và sau đó đối tượng của lớp con có thể truy cập các phương thức và thuộc tính của lớp cha. Example: class

Lưu ý: Để biết thêm thông tin, hãy tham khảo kế thừa trong Python. For more information, refer to Inheritance in Python. Truy cập phương thức lớp cha từ lớp bên trongMột lớp bên trong hoặc lớp lồng nhau là một lớp được xác định bên trong cơ thể của một lớp khác. Nếu một đối tượng được tạo bằng một lớp, đối tượng bên trong lớp gốc có thể được sử dụng. Một lớp có thể có một hoặc nhiều hơn một lớp bên trong. Các loại lớp bên trong: - Nhiều lớp bên trong
- Lớp nội địa đa cấp
Nhiều lớp bên trong: Một lớp chứa nhiều hơn một lớp bên trong. A class containing more than one inner class. Example: class

__ cơ sở __ trong Python là gì?
Python cung cấp thuộc tính __base__ trên mỗi lớp có thể được sử dụng để có được danh sách các lớp mà lớp đã cho.Thuộc tính __base__ của lớp chứa một danh sách tất cả các lớp cơ sở mà lớp đã cho kế thừa.can be used to obtain a list of classes the given class inherits. The __bases__ property of the class contains a list of all the base classes that the given class inherits.
Super () hoạt động như thế nào trong Python?
Hàm Super () trong Python làm cho kế thừa lớp trở nên dễ quản lý và có thể mở rộng hơn.Hàm trả về một đối tượng tạm thời cho phép tham chiếu đến lớp cha bằng từ khóa Super.Hàm Super () có hai trường hợp sử dụng chính: để tránh việc sử dụng lớp siêu (cha mẹ) một cách rõ ràng.The function returns a temporary object that allows reference to a parent class by the keyword super. The super() function has two major use cases: To avoid the usage of the super (parent) class explicitly.
Một lớp cơ sở trong Python là gì?
Một lớp cơ sở trừu tượng là một lớp được sử dụng làm bản thiết kế cho các lớp khác.Các lớp cơ sở trừu tượng là một tính năng mạnh mẽ trong Python vì chúng giúp bạn xác định bản thiết kế cho các lớp khác có thể có điểm chung. |
