How many arguments can be used by email_user function

Without the specific code or context, it's hard to determine the exact number of arguments that the email_user function can take. However, in general, a function in Python can take any number of arguments.

Here's a basic example of a function that takes two arguments:

def email_user(email_address, email_body):
    # code to send email

In this case, the email_user function takes two arguments: email_address and email_body.

But you can also have optional arguments with default values:

def email_user(email_address, email_body, subject="No Subject", cc=None, bcc=None):
    # code to send email

In this case, the email_user function takes five arguments, but the last three are optional.

You can also use *args and **kwargs to allow for an arbitrary number of arguments:

def email_user(email_address, email_body, *args, **kwargs):
    # code to send email

In this case, the email_user function can take any number of arguments.
