Python从MySQL数据库中面抽取试题，生成试卷
疯狂的机器人 人气:0这篇文章主要介绍了Python如何从MySQL数据库中面抽取试题，生成试卷，帮助大家更好的理解和使用python，感兴趣的朋友可以了解下
一、背景
本文章主要是分享如何使用Python从MySQL数据库中面抽取试题，生成的试卷每一份都不一样。
二、准备工作
1.安装Python3
下载地址：https://www.python.org/downloads/windows/
2.安装库
pip install python-docx==0.8.10
pip install PyMySQL==1.0.2
3.试题库.xlsx
开发程序前需要先收集试题，本文是将试题收集存放MySQL数据库中，格式如下：
