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：

 1 import MySQLdb
 2 
 3 conn = MySQLdb.connect(
 4     host='fjkdasjfkdas.aliyuncs.com',
 5     port=3306,
 6     user='fdasf',
 7     passwd='fdasfda',
 8     db='datav',
 9     charset='utf8'
10 )
11 
12 cur = conn.cursor()
13 
14 f = open('test.txt', 'rt')   # 读取文件
15 lines = f.readlines()
16 lists = []   # 定义一个数组
17 for line in lines:
18     s = (str(line.split(',')[0]),int(line.split(',')[1]))   # 构造一个元组
19     print(s)
20     lists.append(s)  # 将元组添加到数组中
21 
22 print(lists)
23 cur.executemany(f"insert into zy_1(name, score) values(%s,%s)",lists)  # 批量插入
24 conn.commit()
25 
26 cur.close()
27 conn.close()
