Python-Can'；无法连接到MS SQL

当我尝试连接到MS SQL时，出现以下错误：

> pyodbc.Error: ('08001', '[08001] [Microsoft][ODBC Driver 13 for SQL
> Server]SQL Server Network Interfaces: Error Locating Server/Instance
> Specified [xFFFFFFFF].  (-1) (SQLDriverConnect); [HYT00]
> [Microsoft][ODBC Driver 13 for SQL Server]Login timeout expired (0);
> [08001] [Microsoft][ODBC Driver 13 for SQL Server]A network-related or
> instance-specific error has occurred while establishing a connection
> to SQL Server. Server is not found or not accessible. Check if

> (-1)')

如何解决此错误并最终连接到数据库

在我的例子中，通过在服务中激活

sqlserver（SQLEXPRESS）

解决了这个问题。事实证明，当计算机启动时，它不会自动打开
