python - 如何在每封电子邮件发送后让代码暂停 5 秒

问题描述

每次发送电子邮件时，我都需要代码休眠 5 秒，当我使用它时，sleep(5)它只会发送所有电子邮件，然后暂停。

编码：

import pandas as pd
import smtplib
from time import sleep

SenderAddress='<xxxx@gmail.com>'

e = pd.read_excel("C:xxx/Email.xlsx")
sleep(5)
emails = e['Emails'].values
server = smtplib.SMTP("smtp.gmail.com:587")
server.starttls()
server.login('xxx@gmail.com', 'xxxxx')

msg = 'Testing the code'

subject = "Congratulations"
body = "Subject: {}\n\n{}".format(subject,msg)
for email in emails:
  server.sendmail(SenderAddress, email, body)
server.quit()

解决方案

尝试将 sleep 方法转移到循环体。像这样

import pandas as pd
import smtplib
from time import sleep

SenderAddress='<xxxx@gmail.com>'

e = pd.read_excel("C:xxx/Email.xlsx")
emails = e['Emails'].values
server = smtplib.SMTP("smtp.gmail.com:587")
server.starttls()
server.login('xxx@gmail.com', 'xxxxx')

msg = 'Testing the code'

subject = "Congratulations"
body = "Subject: {}\n\n{}".format(subject,msg)
for email in emails:
  server.sendmail(SenderAddress, email, body)
  sleep(5)
server.quit()
