This method is used to convert from one encoding scheme, in which argument string is encoded to the desired encoding scheme. This works opposite to the encode. It accepts the encoding of the encoding string to decode it and returns the original string.

encoding : Specifies the encoding on the basis of which decoding has to be performed.
error : Decides how to handle the errors if they occur, e.g ‘strict’ raises Unicode error in case of exception and ‘ignore’ ignores the errors occurred.

Lưu bài viết Returns the original string from the encoded string.

Bàn luận

Decode () là một phương thức được chỉ định trong các chuỗi trong Python 2. Phương thức này được sử dụng để chuyển đổi từ một sơ đồ mã hóa, trong đó chuỗi đối số được mã hóa thành sơ đồ mã hóa mong muốn. Điều này hoạt động đối diện với mã hóa. Nó chấp nhận mã hóa của chuỗi mã hóa để giải mã nó và trả về chuỗi gốc.

Ứng dụng: Mã hóa và giải mã cùng nhau có thể được sử dụng trong các ứng dụng đơn giản lưu trữ mật khẩu ở phía sau và nhiều ứng dụng khác như mật mã liên quan đến việc giữ bí mật thông tin. Một minh chứng nhỏ của ứng dụng mật khẩu được mô tả dưới đây.
Encoding and decoding together can be used in the simple applications of storing passwords in the back end and many other applications like cryptography which deals with keeping the information confidential.
A small demonstration of the password application is depicted below.
