读取txt写入csv，读取csv写入mysql

首先创建一个数据库demo，在建立一个有no（自增）,name,birthday,department的表student：

CREATE DATABASE demo;
USE demo;
CREATE TABLE student(
  NO INT(11) PRIMARY KEY NOT NULL AUTO_INCREMENT,
  NAME VARCHAR(20) NOT NULL,
  birthday DATE,
  department VARCHAR(50) NOT NULL
) ENGINE=INNODB  DEFAULT CHARSET=utf8

demo.py代码如下(附有注释，请放心使用):

import pymysql
'''#把TXT文件变成csv
with open("aa.txt","r") as a:
    data = a.readlines()
with open("aa.csv","w") as b:
    for i in data:
        b.write(i)'''


#读取csv
with open("aa.csv","r") as c:
    data= c.readlines()
    data_list = []
    for i in data:
        tp=tuple(i.strip().split(","))
        data_list.append(tp)
    insert_list=data_list[1:]
    print(insert_list)

with pymysql.connect(host='localhost',
                         port=3306,
                         user='root',
                         password='1234',
                         database='demo',
                         charset='utf8') as conn:
        sql = "INSERT INTO student values(NULL,%s,%s,%s)"
        cur=conn.cursor()
        cur.executemany(sql,insert_list)
        conn.commit()
