ject() 必须从注入上下文中调用

一篇关于 ject() 函数的文章，并添加案例代码。

python
class Logger:
    def __init__(self, log_file):
        self.log_file = log_file
    
    def log(self, message):
        with open(self.log_file, 'a') as file:
            file.write(message + '\n')
class Database:
    def __init__(self, db_name):
        self.db_name = db_name
    
    def connect(self):
        print(f"Connecting to database: {self.db_name}")
def inject(logger, database):
    logger.log("Injecting dependencies...")
    database.connect()
def main():
    logger = Logger('log.txt')
    database = Database('my_database')
    
    inject(logger, database)
if __name__ == "__main__":
    main()
