Hướng dẫn how do i remove special characters from a json string in python? - làm cách nào để xóa các ký tự đặc biệt khỏi chuỗi json trong python?

Đây là tệp JSON của tôi

{
    "highest_table": {
        "items": [{
                "key": "Human 1",
                "columns": {
                    "Na$me": "Tom",
                    "Description[ms/2]": "Table Number One on the Top",
                    "A&ge": "24",
                    "Ge_nder": "M"
                }
            },
            {
                "key": "Human 2",
                "columns": {
                    "Na$me": "John",
                    "Description[ms/2]": "Table Number One on the Top",
                    "A&ge": "23",
                    "Ge_nder": "M"
                }
                }
        ]
    }
}

Mục tiêu là xóa bất kỳ và tất cả các ký tự đặc biệt trong tên cột [hoặc nếu dễ dàng hơn bất kỳ ký tự đặc biệt nào trong tệp .json] và trả về tệp .json. Suy nghĩ ban đầu của tôi là chuyển đổi nó thành gấu trúc, xóa các ký tự đặc biệt trong tiêu đề cột và chuyển đổi nó trở lại tệp .json.

Đây là những gì tôi đã thử cho đến nay. Cả hai chỉ in một dòng duy nhất.

import json
from pandas.io.json import json_normalize    

data_file = r"C:\characters.json"

with open[data_file] as data_file:    
    data = json.load[data_file]  

df = json_normalize[data]  

-

data_file = r"C:\characters.json"

df = pd.read_json[data_file]  

Làm cách nào tôi có thể trích xuất các cột, xóa các ký tự đặc biệt và đặt chúng trở lại trong tệp .json?

Các ký tự sau đây là các ký tự dành riêng và không thể được sử dụng trong JSON và phải được thoát ra đúng cách để được sử dụng trong các chuỗi.

  • Backspace được thay thế bằng \ b to be replaced with \b

  • Nguồn cấp dữ liệu hình thức được thay thế bằng \ f to be replaced with \f

  • Dòng mới được thay thế bằng \ n to be replaced with \n

  • Vận chuyển trở lại để được thay thế bằng \ r to be replaced with \r

  • Tab được thay thế bằng \ t to be replaced with \t

  • Báo giá kép được thay thế bằng \ " to be replaced with \"

  • Backslash để được thay thế bằng \\ to be replaced with \\

Phương thức jsonObject.Scape [] có thể được sử dụng để thoát khỏi các từ khóa dành riêng như vậy trong chuỗi JSON. Sau đây là ví dụ - method can be used to escape such reserved keywords in a JSON String. Following is the example −

Thí dụ

import org.json.simple.JSONObject;

public class JsonDemo {
   public static void main[String[] args] {
      JSONObject jsonObject = new JSONObject[];
      String text = "Text with special character /\"\'\b\f\t\r\n.";
      System.out.println[text];
      System.out.println["After escaping."];
      text = jsonObject.escape[text];
      System.out.println[text];
   }
}

Đầu ra

Text with special character /"'
.
After escaping.
Text with special character \/\"'\b\f\t\r\n.

Vấn đề chung mà các lập trình viên phải đối mặt là loại bỏ các ký tự không mong muốn khỏi một chuỗi bằng Python. Nhưng đôi khi yêu cầu ở trên và yêu cầu loại bỏ hơn 1 nhân vật, nhưng một danh sách các nhân vật độc hại như vậy. Đây có thể ở dạng ký tự đặc biệt để xây dựng lại mật khẩu hợp lệ và nhiều ứng dụng khác có thể. Vì vậy, nhiệm vụ của chúng tôi là loại bỏ các ký tự không mong muốn khỏi chuỗi.

Xóa ký hiệu khỏi chuỗi bằng str.alsalnum []

Phương thức Python String isalnum [] kiểm tra xem tất cả các ký tự trong một chuỗi nhất định có phải là chữ và số hay không. Nó trả về một boolean là đúng - nếu tất cả các ký tự là chữ và khác hoặc sai - nếu một hoặc nhiều ký tự không phải là chữ và số.

Xóa ký hiệu khỏi chuỗi bằng cách sử dụng thay thế [] & nbsp;

Người ta có thể sử dụng str.replace [] bên trong một vòng lặp để kiểm tra BAD_CHAR và sau đó thay thế nó bằng chuỗi trống do đó loại bỏ nó. Đây là cách tiếp cận cơ bản nhất và không hiệu quả trên quan điểm hiệu suất.
