1、加载库
import platform, sys import pandas as pd import pymysql
2、显示环境配置
3、连接数据库
4、查询数据库 show databases
函数式查找
def show_databases(): sql = 'show databases;' try: connection = connection # 连接 except: connection = pymysql.connect(**config) cursor = connection.cursor() # 创建光标 cursor.execute(sql) # 执行查询 dbs = cursor.fetchall() header = cursor.description[0][0] df = pd.DataFrame([db for db, in dbs], columns=[header]) # 创建数据框 return df
调用函数
