批量插入数据，两种方法：

• execute()
• executemany()

executemany()效率远远高于execute()，推荐使用executemany()

代码如下：

import MySQLdb

conn = MySQLdb.connect(
    host='fjkdasjfkdas.aliyuncs.com',
    port=3306,
    user='fdasf',
    passwd='fdasfda',
    db='datav',
    charset='utf8'
)

cur = conn.cursor()

f = open('test.txt', 'rt')   # 读取文件
lines = f.readlines()
lists = []   # 定义一个数组
for line in lines:
    s = (str(line.split(',')[0]),int(line.split(',')[1]))   # 构造一个元组
    print(s)
    lists.append(s)  # 将元组添加到数组中

print(lists)
cur.executemany(f"insert into zy_1(name, score) values(%s,%s)",lists)  # 批量插入
conn.commit()

cur.close()
conn.close()
