# Import the email modules we'll need

from email.parser import BytesParser, Parser

from email.policy import default

# If the e-mail headers are in a file, uncomment these two lines:

# with open(messagefile, 'rb') as fp:

# headers = BytesParser(policy=default).parse(fp)

# Or for parsing headers in a string (this is an uncommon operation), use:

headers = Parser(policy=default).parsestr(

'From: Foo Bar <user@example.com>\n'

'To: <someone_else@example.com>\n'

'Subject: Test message\n'

'\n'

'Body would go here\n')

# Now the header items can be accessed as a dictionary:

print('To: {}'.format(headers['to']))

print('From: {}'.format(headers['from']))

print('Subject: {}'.format(headers['subject']))

# You can also access the parts of the addresses:

print('Recipient username: {}'.format(headers['to'].addresses[0].username))

print('Sender name: {}'.format(headers['from'].addresses[0].display_name))
