Parsing multiple "To:" from raw email in Python

Im using the email module with Python3.7 to parse a raw email.

The value for the To: field is the string 

import email
msg = email.message_from_file(fh)
print(msg.get('To')) 
#---> "name a" <[email protected]>,\n "name b"\n\t<[email protected]>

What would be the easiest and fail-proof way to obtain a list of To: addresses like:

["[email protected]", "[email protected]"]

Emails in Python are stored in a data structure similar to a multidict with case-insensitive keys. Recipient addresses are stored in the named header field "to".

So, the easiest way is to use EmailMessage.get_all():

>>> msg.get_all("to")
["[email protected]", "[email protected]"]

This basic usage assumes the email message was parsed correctly in the first place. The output shown in OP's question suggests that they have a problem earlier on (corrupt input data format), because the email from file was not parsed correctly.

You can use email.utils.getaddresses on msg.get('To')... eg:

to_list = msg.get('To')
emails = email.utils.getaddresses([to_list])

Will give you (given your example) 2-tuples of:

[('name a', '[email protected]'), ('name b', '[email protected]')]
