    # Returns the number of keys in object o on success, and -1 on

    # is equivalent to the Python expression "len(o)".

    # Remove the mapping for object key from the object o. Return -1

    # Remove the mapping for object key from the object o. Return -1
    # on failure. This is equivalent to the Python statement "del

    # On success, return 1 if the mapping object has the key key and 0
    # otherwise. This is equivalent to the Python expression
    # "o.has_key(key)". This function always succeeds.

    object PyMapping_Items(object o)
    # Return value: New reference.
    # On success, return a list of the items in object o, where each
    # item is a tuple containing a key-value pair. On failure, return
    # NULL. This is equivalent to the Python expression "o.items()".

    object PyMapping_GetItemString(object o, char *key)
    # Return value: New reference.
    # Return element of o corresponding to the object key or NULL on
    # failure. This is the equivalent of the Python expression
    # "o[key]".
