本文实例为大家分享了python3邮件群发excel附件的具体代码,供大家参考,具体内容如下

连接、查询mysql,导入到excel文件,定时群发邮件与附件。 主要用到pymysql ,smtplib , xlwt

#1、导入模块


import pymysql #Python3的mysql模块,Python2 是mysqldb
import os
import datetime #定时发送,以及日期
import shutil #文件操作
import smtplib #邮件模块
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
from email.header import Header
import time
import xlwt #excel写入

#2、连接并查询mysql


def eMysql(mysql_host,mysql_port,mysql_user,mysql_password,mysql_db,sql):
 try:
 db = pymysql.connect(host=mysql_host,port=mysql_port,user=mysql_user, password=mysql_password, db=mysql_db,charset = 'utf8')#连接数据库编码注意是utf8,不然中文结果输出会乱码
 print("MYSQL CONNECTED.")# 连接数据库
 cursor = db.cursor()# 使用cursor()方法获取操作游标
 cursor.execute(sql)# 执行SQL语句
 print('SQL EXECUTED')
 results = cursor.fetchall()# 结果
 return results
 print('RESULTS EXECUTED')
 db.close() # 关闭数据库连接
 print('MYSQL CLOSED')
 except:
 print('SQL FAILED')

#3、写入excel


def eWrite(fLocate,results,file_sheet,file_subject,style0):
 try:
 if os.path.exists(fLocate):
 os.remove(fLocate) # 如果文件存在,则删除
 f = xlwt.Workbook(encoding='utf-8') #打开excel文件
 fs = f.add_sheet(file_sheet) #sheet名
 subject = list(file_subject) #列表化
 for i in range(len(subject)): #找到日期列
 if '日期' in subject[i]:
 col_num=i
 for i in range(len(subject)): #sheet标题
 fs.write(0, i, subject[i])

 for i in range(len(results)): #sheet数据,日期列格式为date
 for j in range(len(results[0])):
 if j== col_num:
 fs.write(i + 1, j, results[i][j],style0)
 else:
 fs.write(i + 1, j, results[i][j])


 for i in range(10): #单元格宽度为
 fs.col(i).width=3333

 print("WRITE FINISHED")
 f.save(fLocate)
 except :
 print ("WRITE FAILED")

#4、发送邮件


def eSend(sender,receiver,username,password,smtpserver,subject,e_content,file_path,file_name):
 try:
#邮件头
 message = MIMEMultipart()
 message['From'] = sender#发送
 message['To'] = ",".join(receiver)#收件
 message['Subject'] = Header(subject, 'utf-8')
 message.attach(MIMEText(e_content, 'plain', 'utf-8'))# 邮件正文

# 构造附件
 att1 = MIMEText(open(file_path+file_name,'rb').read(), 'base64', 'utf-8')
 att1["Content-Type"] = 'application/octet-stream'
 att1["Content-Disposition"] = "attachment;filename="+file_name
 message.attach(att1)

#执行
 smtp = smtplib.SMTP()
 smtp.connect(smtpserver) #连接服务器
 smtp.login(username, password) #登录
 smtp.sendmail(sender, receiver, message.as_string()) #发送
 smtp.quit()
 print("SEND")
 except:
 print("SEND FAILED")

#5、配置与执行


while True:
#配置
 #__time_____
 ehour=5#定时小时
 emin=21#定时分钟
 esec=41#定时秒
 current_time = time.localtime(time.time()) #当前时间date
 cur_time = time.strftime('%H%M', time.localtime(time.time())) #当前时间str
 #__mysql_____
 mysql_host = mysql_host #登录host
 mysql_port =mysql_port #登录port
 mysql_user = mysql_user #登录名
 mysql_password = mysql_password #登录密码
 mysql_db = mysql_db #数据库
 sql = sql.encode('utf-8') #sql查询语句编码
 #__email_____
 sender = sender #发件人邮箱
 receiver = ['453032441@qq.com'] #收件人邮箱,可以多个(列表形式)群发
#
 username = username #发件人姓名
 password = password #smtp密码,qq是给你分配一串,163是自己设置
 smtpserver = smtpserver #邮箱服务器
 subject = "Hey,here's something interesting" #邮件标题
 e_content = '{0:^27}\n{1:^27}\n{2:^25}\n{3:^25}'.format('i','/ \\','(-----)','(--------)') #邮件正文 #邮件正文
 #__file_____
 file_path = "D:/" #文件位置
 file_name="shit.xls" #文件名
 fLocate = file_path + file_name #文件路径
 file_subject='Gave', 'you', 'a', 'piece', 'of', 'shit.' #sheet标题
 file_sheet='ok' #sheet名
 style0=xlwt.XFStyle()
 style0.num_format_str='YYYY-MM-DD'
#操作
 if ((current_time.tm_hour == ehour) and (current_time.tm_min == emin) and (current_time.tm_sec == esec)):
 print ("START")
 results=eMysql(mysql_host,mysql_port,mysql_user,mysql_password,mysql_db,sql)
 eWrite(fLocate, results, file_sheet, file_subject,style0)
 eSend(sender, receiver, username, password, smtpserver, subject, e_content, file_path,file_name)
 print(cur_time)
 time.sleep(1)
