Sending Emails with Integer Subjects/Verifying Numbers: Python

Question

I am working on a personal project which you you enter credentials (to simulate signing-up to a website) and it stores them in a Google Sheets Document. I use smtplib to send an email with a verification code. I have faced two problems while doing this: 1. I have a variable, verification_code, which I set to my verification code (which I plan to be random in the future). The problem is that when I try to send it as an integer, I get this error:

Traceback (most recent call last):
  File "/Users/user/PycharmProjects/sign-up test enviroment/main.py", line 92, in <module>
    verify_email()
  File "/Users/user/PycharmProjects/sign-up test enviroment/main.py", line 62, in verify_email
    msg.attach(MIMEText(message, 'plain'))
  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/email/mime/text.py", line 34, in __init__
    _text.encode('us-ascii')
AttributeError: 'int' object has no attribute 'encode'

But, when I set the integer to a string using '', it sends just fine. The problem is that I cannot do that since I try checking to see if the entred variable, entered_code, (which is entered through user input), matched the pre-defined integer set to the variable verification_code. Here is my code which I use to check to see if the code entered by the user matches the code that was pre-defined (verification_code):

def enter_verification_code():
    global verification_code, entered_code
    entered_code = int(input("Please enter the verification code sent to " + user_email + ': '))
    if verification_code == entered_code:
        print('Thank you for verifying your account!')
        store_info()
        exit()
    elif verification_code != entered_code:
        entered_code = int(input("Please enter the verification code sent to " + user_email + ': '))
        enter_verification_code()

What I am wondering is if there is a way to send my variable as an integer through the email, or if there is a better way to verify that the entered code matches the code that I defined at the start of my project. Thanks!

You can use str() so the user can paste the code then convert it using int() to verify it in your code

def enter_verification_code():
    global verification_code, entered_code
    entered_code = input("Please enter the verification code sent to " + user_email + ': ')
    if verification_code == int(entered_code):
        print('Thank you for verifying your account!')
        store_info()
        exit()
    elif verification_code != entered_code:
        entered_code = int(input("Please enter the verification code sent to " + user_email + ': '))
        enter_verification_code()
