pymysql插入示例数据name, age,sex

使用本地mysql做简单测试时需要创建的示例数据，于是用python编写了mysql的连接与批量新增数据的过程，其中测试表的设计如下：

源码

import random
import pymysql

# 连接数据库
try:
    conn = pymysql.connect(host="localhost", user="root", password="1234", database="test")
except RuntimeError as e:
    print('connect failed', e)
    exit(0)
print('connect success')
cursor = conn.cursor()

# 创建示例数据
datas = []
for idx in range(97, 123):
    name = chr(idx) * 2
    age = random.randint(20, 30)
    sex = ['male', 'female'][random.randint(0, 1)]
    datas.append((name, age, sex))
    
# 插入示例数据
sql = 'insert into t_test (name, age, sex) values (%s, %s, %s);'
ret = cursor.executemany(sql, datas)
conn.commit()

# 查询数据表数据
cursor.execute("select * from t_test;")
print(ret, cursor.fetchall())

# 关闭
cursor.close()
conn.close()
