Tôi đang học Python qua sách và internet và tôi bị mắc kẹt trong một vấn đề lớp học.
2 câu hỏi:
- Làm cách nào để tạo một thể hiện của một lớp trong lớp khác [riêng biệt]?
- Làm cách nào để vượt qua các biến giữa lớp và lớp lồng nhau [?]?
Khi tôi cố gắng tạo một thể hiện của một lớp trong lớp khác [riêng biệt], tôi có thể thực hiện trong một phương thức. Đây là mã:
import os
class FOO[]:
def __init__[self]:
self.values = [2, 4, 6, 8]
def do_something[self, x, y]:
os.system["clear"]
z = self.values[x] * self.values[y]
print "%r * %r = %r" % [self.values[x], self.values[y], z]
class BAR[]:
def __init__[self]:
pass
def something_else[self, a, b]:
foo1 = FOO[]
foo1.do_something[a, b]
bar = BAR[]
bar.something_else[1, 2]
Tuy nhiên, điều này sẽ cho phép tôi truy cập vào lớp FOO và đó là thông tin trong các phương thức thanh khác? Nếu vậy, làm thế nào?
Tôi đã thử những điều sau và gặp lỗi:
import os
class FOO[]:
def __init__[self]:
self.values = [2, 4, 6, 8]
def do_something[self, x, y]:
os.system["clear"]
z = self.values[x] * self.values[y]
print "%r * %r = %r" % [self.values[x], self.values[y], z]
class BAR[]:
def __init__[self]:
foo1 = FOO[]
def something_else[self, a, b]:
foo1.do_something[a, b]
bar = BAR[]
bar.something_else[1, 2]
Đây là lỗi:
Traceback [most recent call last]:
File "cwic.py", line 22, in
bar.something_else[1, 2]
File "cwic.py", line 19, in something_else
foo1.do_something[a, b]
NameError: global name 'foo1' is not defined
Tôi nhận được cùng một lỗi khi tôi sử dụng:
def __init__[self]:
self.foo1 = FOO[]
Ngoài ra, làm thế nào tôi nên chuyển 'giá trị' từ lớp này sang lớp khác?
Xin vui lòng cho tôi biết nếu cách tiếp cận chung và/hoặc cú pháp của tôi là sai.

Lớp bên trong ở Python
Một lớp được xác định trong một lớp khác được gọi là lớp bên trong hoặc lớp lồng nhau. Nếu một đối tượng được tạo bằng cách sử dụng lớp bên trong lớp con thì đối tượng cũng có thể được sử dụng bởi lớp cha hoặc lớp gốc. Một lớp cha có thể có một hoặc nhiều lớp bên trong nhưng nhìn chung các lớp bên trong được tránh.inner class or nested class. If an object is created using child class means inner class then the object can also be used by parent class or root class. A parent class can have one or more inner classes but generally inner classes are avoided.
Chúng ta có thể làm cho mã của chúng ta trở nên định hướng đối tượng hơn bằng cách sử dụng một lớp bên trong. Một đối tượng duy nhất của lớp có thể chứa nhiều đối tượng phụ. Chúng tôi có thể sử dụng nhiều đối tượng phụ để cung cấp một cấu trúc tốt cho chương trình của chúng tôi.
Example:
- Đầu tiên, chúng tôi tạo một lớp và sau đó là hàm tạo của lớp.
- Sau khi tạo một lớp, chúng tôi sẽ tạo một lớp khác trong lớp đó, lớp bên trong một lớp khác sẽ được gọi là lớp bên trong.

Tại sao lớp bên trong?
Cho nhóm hai hoặc nhiều lớp. Giả sử chúng ta có hai lớp từ xa và pin. Mỗi điều khiển từ xa đều cần một pin nhưng pin không có won từ xa được sử dụng. Vì vậy, chúng tôi làm cho pin trở thành một lớp bên trong đến điều khiển từ xa. Nó giúp chúng tôi lưu mã. Với sự giúp đỡ của lớp bên trong hoặc lớp lồng nhau, chúng ta có thể che giấu lớp bên trong khỏi thế giới bên ngoài. Do đó, ẩn mã là một tính năng tốt khác của lớp bên trong. Bằng cách sử dụng lớp bên trong, chúng ta có thể dễ dàng hiểu các lớp vì các lớp có liên quan chặt chẽ. Chúng tôi không cần phải tìm kiếm các lớp trong toàn bộ mã, tất cả đều gần như cùng nhau. Mặc dù các lớp bên trong hoặc lồng nhau không được sử dụng rộng rãi trong Python, nhưng nó sẽ là một tính năng tốt hơn để thực hiện mã vì việc tổ chức khi chúng ta sử dụng lớp bên trong hoặc lớp lồng nhau.Multiple inner class
Python3
Các loại lớp bên trong như sau: & nbsp;

Tại sao lớp bên trong?
Cho nhóm hai hoặc nhiều lớp. Giả sử chúng ta có hai lớp từ xa và pin. Mỗi điều khiển từ xa đều cần một pin nhưng pin không có won từ xa được sử dụng. Vì vậy, chúng tôi làm cho pin trở thành một lớp bên trong đến điều khiển từ xa. Nó giúp chúng tôi lưu mã. Với sự giúp đỡ của lớp bên trong hoặc lớp lồng nhau, chúng ta có thể che giấu lớp bên trong khỏi thế giới bên ngoài. Do đó, ẩn mã là một tính năng tốt khác của lớp bên trong. Bằng cách sử dụng lớp bên trong, chúng ta có thể dễ dàng hiểu các lớp vì các lớp có liên quan chặt chẽ. Chúng tôi không cần phải tìm kiếm các lớp trong toàn bộ mã, tất cả đều gần như cùng nhau. Mặc dù các lớp bên trong hoặc lồng nhau không được sử dụng rộng rãi trong Python, nhưng nó sẽ là một tính năng tốt hơn để thực hiện mã vì việc tổ chức khi chúng ta sử dụng lớp bên trong hoặc lớp lồng nhau.

Làm thế nào để bạn sử dụng một đối tượng của một lớp trong một lớp khác trong Python?
Nếu chúng ta có hai lớp khác nhau và một trong số này được xác định một lớp khác về việc gọi hàm tạo. Sau đó, phương thức và thuộc tính của một lớp khác có thể được truy cập bởi các đối tượng lớp đầu tiên [nghĩa là các đối tượng trong các đối tượng]. Ở đây trong ví dụ dưới đây, chúng ta học cách truy cập đối tượng [các phương thức và thuộc tính của nó] trong một đối tượng.the method and attributes of another class can be accessed by first class objects [ i.e; objects within objects ]. Here in the below example we learn to access object [its methods and attributes] within an object.
Làm thế nào để bạn tạo một đối tượng của một lớp khác trong Python?
Một lớp giống như một hàm tạo đối tượng hoặc "bản thiết kế" để tạo các đối tượng ...
Tạo một lớp học.Để tạo một lớp, hãy sử dụng lớp từ khóa: ....
Tạo đối tượng.Bây giờ chúng ta có thể sử dụng lớp có tên MyClass để tạo các đối tượng: ....
Tham số tự.....
Sửa đổi thuộc tính đối tượng.....
Xóa thuộc tính đối tượng.....
Xóa đối tượng ..
Phương pháp __ init __ là gì?
