通过以上步骤,你已经学会了如何在 Python 中使用setup函数连接数据库。尽管上述示例是围绕 MySQL 编写的,但你可以根据具体情况,使用其它数据库(如 PostgreSQL、SQLite 等)只需更改相关库和连接参数即可。在以后的项目中,尝试自己动手实现这个过程,这是提高你编程能力的重要步骤。 希望这篇文章能够为你在数据库连接方面...
使用pandas库进行数据库备份(以SQLite为例): import pandas as pd import sqlite3 def backup_database(db_name, backup_name): conn = sqlite3.connect(db_name) df = pd.read_sql_query("SELECT * FROM your_table_name", conn) conn.close() df.to_csv(backup_name, index=False) db_name = '...
示例代码: # test_database.py import pytest import sqlite3 @pytest.fixture(scope="module") def db_connection(): print("创建数据库连接") conn = sqlite3.connect(":memory:") yield conn print("关闭数据库连接") conn.close() @pytest.fixture(scope="function") def db_cursor(db_connection): ...
Setup和teardown通常用于执行一些测试前的准备工作和测试后的清理工作,例如初始化测试数据、启动和关闭测试数据库连接等。在许多自动化测试框架中,如unittest(Python标准库之一)和nose(第三方库)等,都提供了setup和teardown方法。例如,在unittest中,可以使用setUpClass和tearDownClass方法来分别在测试类运行前和运行后执行...
