18.5. mhlib — Access to MH mailboxes - Python 2.7.18 documentation 编辑

Deprecated since version 2.6: The mhlib module has been removed in Python 3. Use the mailbox instead.

The mhlib module provides a Python interface to MH folders and their contents.

The module contains three basic classes, MH, which represents a particular collection of folders, Folder, which represents a single folder, and Message, which represents a single message.

class mhlib.MH([path[, profile]])

MH represents a collection of MH folders.

class mhlib.Folder(mh, name)

The Folder class represents a single folder and its messages.

class mhlib.Message(folder, number[, name])

Message objects represent individual messages in a folder. The Message class is derived from mimetools.Message.
