Python: Convert email address list to send email

Question

I have email address list as below:

email_list = [a@gmail.com, b@gmail.com, c@gmail.com]

I converted with below:

email_string = ''.join(str(e) for e in email_list)

But I got emails are a@gmail.com b@gmail.com c@gmail.com which can not be received email, I would like to receive email successfully(Exchange mail server).

my function is as below, I use Mailbox of exchangelib :

to_recipients=[Mailbox(email_address=' '.join(str(e) for e in list(test.user.all().values_list('email', flat=True))))]

Answer 1

You have the right idea - just use a semicolon instead of an empty string when joining:

email_string = ';'.join(str(e) for e in email_list)
# Here ---------^

Answer 2

While it appears that the apostrophes contain a space they actually do not.

email_string = ''.join(str(e) for e in email_list)

is different than

email_string = ' '.join(str(e) for e in email_list)
