Question

I’m creating a Python mailing List, but I had a problem at the end of function.

Problem is, the List must be like this:

['[e-mail]', '[e-mail]', '[e-mail]']

My current code:

mailinputs = raw_input('Enter all mails with comma: ')
receivers = [mailinputs]

If you type:

'[e-mail]', '[e-mail]', '[e-mail]'

An error comes up like this:

Probe failed: Illegal envelope To: address (invalid domain name):

Else, If you type:

[e-mail], [e-mail], [e-mail]

Only [e-mail] receives the mail.

What should I do?

Answer 1

The return of raw_input() is a string. You need to split it on the comma, then you’ll get a list:

>>> '[e-mail],[e-mail],[e-mail]'.split(',')
['[e-mail]', '[e-mail]', '[e-mail]']

So in your example:

mailinputs = raw_input('Enter all mails with comma: ')
receivers = mailinputs.split(',')

Another step can be done to remove any whitespace before/after each email:

mailinputs = raw_input('Enter all mails with comma: ')
receivers = [x.strip() for x in mailinputs.split(',')]
