python之mysql数据库操作--创建一个table

首先导入pymysql包， 然后连接数据库进行操作

​import pymysql
db = pymysql.connect(host='localhost', user='root', password='cheng1130', port=3306)
cursor = db.cursor()
cursor.execute('SELECT VERSION()')
data = cursor.fetchone()
print('Database version:', data)
cursor.execute("create database Testdb default character set utf8MB4")
db.close()     #查看数据库是否连接，及其mysql数据库版本
sql = 'create table if not exists students(id varchar(255) not null,name varchar(255) not null,age int not null,primary key(id))'
cursor.execute(sql)​
