# 18.5. `mhlib` — Access to MH mailboxes

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`.

## 18.5.1. MH Objects

`MH` instances have the following methods:

`MH.` `error`(format[, ...])

  Print an error message – can be overridden.

`MH.` `getprofile`(key)

  Return a profile entry (`None` if not set).

`MH.` `getpath`()

  Return the mailbox pathname.

`MH.` `getcontext`()

  Return the current folder name.

`MH.` `setcontext`(name)

  Set the current folder name.

`MH.` `listfolders`()

  Return a list of top-level folders.

`MH.` `listallfolders`()

  Return a list of all folders.

`MH.` `listsubfolders`(name)

  Return a list of direct subfolders of the given folder.

`MH.` `listallsubfolders`(name)

  Return a list of all subfolders of the given folder.

`MH.` `makefolder`(name)

  Create a new folder.

`MH.` `deletefolder`(name)

  Delete a folder – must have no subfolders.

`MH.` `openfolder`(name)

  Return a new open folder object.

## 18.5.2. Folder Objects

`Folder` instances represent open folders and have the following methods:

`Folder.` `error`(format[, ...])

  Print an error message – can be overridden.

`Folder.` `getfullname`()

  Return the folder’s full pathname.

`Folder.` `getsequencesfilename`()

  Return the full pathname of the folder’s sequences file.

`Folder.` `getmessagefilename`(n)

  Return the full pathname of message n of the folder.

`Folder.` `listmessages`()

  Return a list of messages in the folder (as numbers).

`Folder.` `getcurrent`()

  Return the current message number.

`Folder.` `setcurrent`(n)

  Set the current message number to n.

`Folder.` `parsesequence`(seq)

  Parse msgs syntax into list of messages.

`Folder.` `getlast`()

  Get last message, or `0` if no messages are in the folder.

`Folder.` `setlast`(n)

  Set last message (internal use only).

`Folder.` `getsequences`()

  Return dictionary of sequences in folder. The sequence names are used as keys, and the values are the lists of message numbers in the sequences.

`Folder.` `putsequences`(dict)

  Return dictionary of sequences in folder name: list.

`Folder.` `removemessages`(list)

  Remove messages in list from folder.

`Folder.` `refilemessages`(list, tofolder)

  Move messages in list to other folder.

`Folder.` `movemessage`(n, tofolder, ton)

  Move one message to a given destination in another folder.

`Folder.` `copymessage`(n, tofolder, ton)
