Python读取数据库写入TXT中(一条数据写入一个TXT文本)

import os

import pymysql

conn = pymysql.connect(
    host='localhost',
    user='root',
    password='123456',
    db='news',
    charset='utf8',
       # autocommit=True,    # 如果插入数据,, 是否自动提交? 和conn.commit()功能一致。
)

def selecttable():
#  **************************数据库查询*****************************
    cur = conn.cursor()
    sql3 = "select * from zh_new limit 100;"  #新闻的条数
    result = cur.execute(sql3)  # 默认不返回查询结果集, 返回数据记录数。
    print(result)
    for i in range(100):
        path_list = ['news', str(i) + '.txt']
        x=cur.fetchone()
        print(x[0])     #新闻标题
        print(x[1])     #新闻内容
        head = ''
        for path in path_list:
            head = os.path.join(head, path)
        print(head)
        with open(head,"w",encoding='UTF-8') as file:   #”w"代表着每次运行都覆盖内容
            file.write(x[0] + "  内容:" + x[1]+"\n")



# 4. 关闭游标
    cur.close()
# 5. 关闭连接
    conn.close()

if __name__=='__main__':
    selecttable()
