🔧 3. 文件读写接口

class FileHandler:    @staticmethod    def write_to_file(filename, content):        with open(filename, 'w') as file:            file.write(content)    @staticmethod    def read_from_file(filename):        with open(filename, 'r') as file:            return file.read()

💡 4. 数据解析器​​​​​​​

import jsonclass JSONParser:    @staticmethod    def parse(json_string):        return json.loads(json_string)    @staticmethod    def stringify(data):        return json.dumps(data)

📊 5. 时间日期处理接口​​​​​​​

from datetime import datetimeclass DateTimeUtils:    @staticmethod    def format_datetime(dt=datetime.now()):        return dt.strftime('%Y-%m-%d %H:%M:%S')

📋 6. 数据加密解密​​​​​​​

from cryptography.fernet import Fernetclass Crypto:    def __init__(self, key):        self.key = key        self.cipher_suite = Fernet(key)    def encrypt(self, data):        return self.cipher_suite.encrypt(data.encode())    def decrypt(self, token):        return self.cipher_suite.decrypt(token).decode()

7. 数据持久化接口（使用SQLite）​​​​​​​

import sqlite3class Database:    def __init__(self, db_name='data.db'):        self.conn = sqlite3.connect(db_name)        self.cursor = self.conn.cursor()    def execute(self, query, data=None):        if data:            self.cursor.execute(query, data)        else:            self.cursor.execute(query)        self.conn.commit()    def fetch_all(self, query):        self.cursor.execute(query)        return self.cursor.fetchall()

📈 8. 图像处理接口​​​​​​​

from PIL import Imageclass ImageProcessor:    @staticmethod    def resize_image(image_path, size=(100, 100)):        img = Image.open(image_path)        img_resized = img.resize(size)        img_resized.save('resized_' + image_path)

🕵️‍♂️ 9. 异常处理接口​​​​​​​

class ErrorHandler:    @staticmethod    def handle_exception(func):        def wrapper(*args, **kwargs):            try:                return func(*args, **kwargs)            except Exception as e:                print(f"Error occurred: {e}")        return wrapper

 10. 配置加载接口​​​​​​​

import yamlclass ConfigLoader:    @staticmethod    def load_config(config_file='config.yaml'):        with open(config_file, 'r') as file:            return yaml.safe_load(file)

代码解释

这些接口不仅能够简化代码结构，还能提高代码的可读性和可测试性。通过将这些接口应用到项目中，你可以轻松地扩展或修改功能，而无需担心对其他部分产生影响。
