本文實例為大家分享了Python3定時發送郵件功能的具體代碼，供大家參考，具體內容如下

1、 導入模塊

import osimport datetime #定時發送，以及日期import shutil #文件操作import smtplib #郵件模塊from email.mime.text import MIMETextfrom email.mime.multipart import MIMEMultipartfrom email.header import Headerimport timeimport xlwt #excel寫入

2、寫入EXCEL

def eWrite(fLocate,file_sheet,file_subject,style0):  try:    if os.path.exists(fLocate):      os.remove(fLocate)  # 如果文件存在，則刪除    f = xlwt.Workbook(encoding='utf-8')  #打開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標題      fs.write(0, i, subject[i])    for i in range(10): #單元格寬度為      fs.col(i).width=3333    print("WRITE FINISHED")    f.save(fLocate)  except :    print ("WRITE FAILED")

3、發送郵件

def eSend(sender,receiver,username,password,smtpserver,subject,e_content,file_path,file_name):  try:#郵件頭    message = MIMEMultipart()    message['From'] = sender#發送    message['To'] = ",".join(receiver)#收件    message['Subject'] = Header(subject, 'utf-8')    message.attach(MIMEText(e_content, 'plain', 'utf-8'))# 郵件正文# 構造附件    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)#執行    smtp = smtplib.SMTP()    smtp.connect(smtpserver) #連接服務器    smtp.login(username, password) #登錄    smtp.sendmail(sender, receiver, message.as_string()) #發送    smtp.quit()    print("SEND")  except:    print("SEND FAILED")

4、配置與執行

while True:#配置  #__time_____  ehour=11#定時小時  emin=49#定時分鐘  esec=50#定時秒  current_time = time.localtime(time.time())   #當前時間date  cur_time = time.strftime('%H%M', time.localtime(time.time()))       #當前時間str  #__mysql_____  #__email_____  sender = '' # 發件人郵箱  receiver = ['453032441@qq.com'] # 收件人郵箱，可以多個（列表形式）群發  username = '' # 發件人姓名  password = '' # smtp密碼，qq是給你分配一串，163是自己設置  smtpserver = '' # 郵箱服務器  subject = "Hey,here's something interesting"   #郵件標題  e_content = '{0:^27}/n{1:^27}/n{2:^25}/n{3:^25}'.format('i','/  //','(-----)','(--------)')  #郵件正文  #__file_____  file_path = "D:/"  #文件位置  file_name="shit.xls"  #文件名  fLocate = file_path + file_name   #文件路徑  file_subject='I', 'MISS', 'U' #sheet標題  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")    eWrite(fLocate, file_sheet, file_subject,style0)    eSend(sender, receiver, username, password, smtpserver, subject, e_content, file_path,file_name)    print(cur_time)  time.sleep(1)
