我们可以在 python 程序中多次使用带有某些参数的用户定义函数吗？

Question

我想在我的 python 程序中针对不同的情况发送邮件，但是我的 'message' （检查程序）在每种情况下都不同，我该如何解决这个问题？我想每次使用相同的用户定义函数发送带有不同消息的邮件，即 sendmail(mail,message)

def sendmail(mail,message):
    port = 587  # For starttls
    smtp_server = "smtp.gmail.com"
    sender_email = "something@gmail.com"
    receiver_email = mail
    password = 'password123'

    context = ssl.create_default_context()
    with smtplib.SMTP(smtp_server, port) as server:
        server.ehlo()  # Can be omitted
        server.starttls(context=context)
        server.ehlo()  # Can be omitted
        server.login(sender_email, password)
        server.sendmail(sender_email, receiver_email, message)

message = f"""\         #my first message
  Subject: Use OTP {no} Dear {extname(am1)}, 
  Use OTP {no} to access your account. 
  Don't share it with someone else. """ 
  sendmail(mail,message) 

  message = f'''\         #my second message
  Subject: ZABANK: Current Balance 
  Dear {extname(am1)}, 
  Your current balance is {extbal(am1)} rupees. ''' 
  sendmail(mail,message)

我最后两次收到第一条消息。此处不需要 mail，因为它是分配给另一个用户定义函数的变量。

您不能调用该功能两次，因为它需要同时登录两次 SMTP，当您已经登录时正在登录您的帐户（因此不会发送第二条消息）。你可以通过迭代你的消息列表来克服这个问题

#please change your funtion name to avoid collision with the smtp.SMTP.sendmail method 
def usersendmail(mail,message):
    port = 587  # For starttls
    smtp_server = "smtp.gmail.com"
    sender_email = "something@gmail.com"
    receiver_email = mail
    password = 'password123'

    context = ssl.create_default_context()
    with smtplib.SMTP(smtp_server, port) as server:
        server.ehlo()  # Can be omitted
        server.starttls(context=context)
        server.ehlo()  # Can be omitted
        server.login(sender_email, password)
        for msg in messagelist:
            server.sendmail(sender_email, receiver_email, msg)

usersendmail("them@gmail.com",["mymessage1","mymessage2"])
