整体思路：

1，读取json文件

2，将数据格式化为dict，取出key，创建数据库表头

3，取出dict的value，组装成sql语句，循环执行

4，执行SQL语句

#python 3.6
# -*- coding:utf-8 -*-
__author__ = 'BH8ANK'import json
import pymysqlconn = pymysql.connect(
host = 'localhost',#mysql服务器地址
port = 3306,#端口号
user = 'root',#用户名
passwd = 'xxxxxx',#密码
db = 'xdb',#数据库名称
charset = 'utf8',#连接编码，根据需要填写
)
cur = conn.cursor()#创建并返回游标#创建表头
sql = "CREATE TABLE daxue (code VARCHAR(32),charge VARCHAR(100),level VARCHAR(100),name VARCHAR(100),remark VARCHAR(100),prov VARCHAR(100));"cur.execute(sql)#执行上述sql命令
a = open(r"D:\alldata.json", "r",encoding='UTF-8')
out = a.read()
tmp = json.dumps(out)
tmp = json.loads(out)
num = len(tmp)
i = 0
while i < num:
code = tmp[i]['code']
charge = tmp[i]['charge']
level = tmp[i]['level']
name = tmp[i]['name']
remark = tmp[i]['remark']
prov = tmp[i]['prov']
value = [code,charge,level,name,remark,prov]
sql_insert = "insert into daxue (code,charge,level,name,remark,prov) values (" + "'"+code+"'" +","+ "'"+charge+"'" + ","+"'"+level+"'" + ","+"'"+name+"'" + ","+"'"+remark+"'" + ","+"'"+prov+"'" + ");"
# sql_insert =("insert into daxue (code,charge,level,name,remark,prov) values (%s,%s,%s,%s,%s,%s);",value)
# sql_insert = sql_insert.encode("utf8")
print(sql_insert) cur.execute(sql_insert) # 执行上述sql命令
i = i+1# print(num)
conn.commit()
conn.close()
