Start with the documentation. The Header() constructor accepts a single
header value, not an entire email message. the decode_header function
also accepts a single header value, not a Header instance.

You maybe want something like

msg = email.message_from_file(open('email_message'))
subj = msg['subject']

Then you could do things like email.header.Header(subj) to create a
Header instance or decode_header(subj) to decode an RFC 2447 encoded
subject.
