Python实现四位数加密：特定算法与数字互换技巧

```python def encrypt_number(num): num_str = str(num) encrypted_num = "" for digit in num_str: digit = int(digit) encrypted_digit = (digit + 10) % 5 encrypted_num += str(encrypted_digit) encrypted_num = encrypted_num[2] + encrypted_num[3] + encrypted_num[0] + encrypted_num[1] return int(encrypted_num) num = int(input("请输入一个四位数: ")) print(encrypt_number(num)) ``` ######[AI写代码神器 | 124点数解答 | 2024-10-21 19:56:16]
