im trying to pass number and operator to the server and pass back the answer using a UDP socket.

i get a 'tuple' object has no attribute 'decode' . on line 20 of the client. (print(answer.decode()).

if i take out the decode and input 5 + 5 it returns (b'10', ('127.0.0.1', 12456)).

can anyone help ve no idea. only been doing this for a week haha! code below

thanks alot.

client-

from socket import *
import socket
serverName = 'Localhost'
serverPort = 12456
clientSocket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
number1 = input ('Input number1: ')
number2 = input ('Input number2: ')
operator = input ('Select an operator: (+ / * -) ')

clientSocket.sendto(number1.encode(),(serverName,serverPort))
clientSocket.sendto(number2.encode(),(serverName,serverPort))
clientSocket.sendto(operator.encode(),(serverName,serverPort))
answer= clientSocket.recvfrom(2048)
print (answer.decode())
clientSocket.close()

server -

from socket import *
import socket
serverName = 'Localhost'
serverPort = 12456
serverSocket = socket.socket(socket.AF_INET,socket.SOCK_DGRAM)
serverSocket.bind(('',12456))
print ('The server is connected')
while 1:
number1, clientAddress = serverSocket.recvfrom(2048)
number2, clientAddress = serverSocket.recvfrom(2048)

operator, clientAddress = serverSocket.recvfrom(2048)

if str(operator) == '+':
answer = int(number1.decode()) + int(number2.decode())
answer = str(answer)
serverSocket.sendto(answer.encode(),clientAddress)
elif str(operator) == '-':
answer = int(number1.decode()) - int(number2.decode())
answer = str(answer)
serverSocket.sendto(answer.encode(),clientAddress)
elif str(operator) == '/':
answer = int(number1.decode()) / int(number2.decode())
answer = str(answer)
serverSocket.sendto(answer.encode(),clientAddress)
elif str(operator) == '*':
answer = int(number1.decode()) * int(number2.decode())
answer = str(answer)
serverSocket.sendto(answer.encode(),clientAddress)
serverSocket.close()

I am creating a Contact page for my django project. forms.py has name, subject, sender and message. Here's the view:

And the form:

<form method="POST">

{%csrf_token%}

{{form.as_p}}

<button type="submit">Send</button>

</form>

After I click Send I get this error: AttributeError: 'tuple' object has no attribute 'encode' and I can't seem to figure out what's wrong despite checking other questions of the same type.

I am using google SMTP server, from this link following its instructions.

I am trying to call the function send_email with the variable message in it and combining it with a string contained in AlertSMSText and assigning it to text as well as html to HTMLEmailBody.

For some reason when I do text = AlertSMSText, message and it gives me the error AttributeError: 'tuple' object has no attribute 'encode' but if I do text = AlertSMSText + message and html = HTMLEmailBody + message it works fine except it ignores \n contained in the string that AlertSMSText has in it.

SendEmailAlert.py

def send_email(message):
  email_subject = JSONFileReader.SubjectEmail  
  sender_add = JSONFileReader.SenderEmail  
  receiver_add = JSONFileReader.ReceiverEmail  
  smsEmail_add = JSONFileReader.SMSEmailAdd  # SMS email
  AlertSMSText = JSONFileReader.AlertSMSText #Alert SMS Text message
  HTMLEmailBody = JSONFileReader.AlertHTMLEmailBody  #Alert Email message in HTML format
  password = JSONFileReader.gmailPass  # Password for the email you're sending from

  # Below is creating the SMTP server object by giving the SMPT server an address and port number
  smtp_server = smtplib.SMTP("smtp.gmail.com", 587)
  smtp_server.ehlo()  # setting the ESMTP protocol
  smtp_server.starttls()  # setting up to TLS connection
  smtp_server.ehlo()  # calling the ehlo() again as encryption happens on calling startttls()
  smtp_server.login(sender_add, password)  # logging into the senders email

  rcpt = smsEmail_add.split(",") + [receiver_add]  # Formats the recipients emails
  # Create message container - the correct MIME type is multipart/alternative.
  msg = MIMEMultipart('alternative')
  msg['Subject'] = email_subject
  msg['From'] = sender_add
  msg['To'] = receiver_add
  msg['Cc'] = smsEmail_add

  message.encode('utf-8')

  # Create the body of the message (a plain-text is for SMS and HTML is for email)
  text = AlertSMSText, message
  html = HTMLEmailBody, message


  # Record the MIME types of both parts - text/plain and text/html.
  part1 = MIMEText(text, 'plain')
  part2 = MIMEText(html, 'html')

  # Attach parts into message container.
  # According to RFC 2046, the last part of a multipart message, in this case
  # the HTML message, is best and preferred.
  msg.attach(part1)
  msg.attach(part2)

  smtp_server.sendmail(sender_add, rcpt, msg.as_string()) #Sends the email

  smtp_server.quit()  #Terminates the SMTP server

 ip= "10.1.50.2"
 send_email(ip + " is down.\n\nPlease reply with 'Ack' to pause alerts for 60 minutes")

In the JSON, the AlertSMSTextvariable equals to "Alert SMS Text": "This is an alert for your services \n\n IP: "

The output when text = AlertSMSText + message is all on one line and ignores newline \n:

This is an alert for your services IP:10.1.50.0 is down. Please reply with 'Ack' to pause alerts for 60 minutes

I want it to be:

This is an alert for your services

IP:10.1.50.0 is down. 

Please reply with 'Ack' to pause alerts for 60 minutes
