Parameters
----------
shared: bool, optional
It defaults to `True`, in which case it uses the shared database
synchronized with Odysee online.
If it is `False` it will use only the local database
to the LBRY Desktop application.
claim_id: bool, optional
It defaults to `False`.
If it is `True` it will print the claim ID (40-character string)
of each claim.
sanitize: bool, optional
It defaults to `False`, in which case it will not remove the emojis
from the name of the claim and channel.
If it is `True` it will remove these unicode characters.
This option requires the `emoji` package to be installed.
file: str, optional
It defaults to `None`.
It must be a writable path to which the summary will be written.
Otherwise the summary will be printed to the terminal.
fdate: bool, optional
It defaults to `False`.
If it is `True` it will add the date to the name of the summary file.
sep: str, optional
It defaults to `;`. It is the separator character between
the data fields in the printed summary. Since the claim name
can have commas, a semicolon `;` is used by default.
server: str, optional
It defaults to `'http://localhost:5279'`.
This is the address of the `lbrynet` daemon, which should be running
in your computer before using any `lbrynet` command.
Normally, there is no need to change this parameter from its default
value.
Returns
-------
dict
It has three keys:
- 'favorites': a dictionary with five keys, 'id', 'items', 'name',
'type', and 'updatedAt'. The 'items' key contains a list with
the individual URIs of the claims in this playlist.
- 'watchlater': a dictionary with the same five keys as 'favorites'.
- 'unpublished': a dictionary containing a variable number
of dictionaries, each of them representing an unpublished playlist.
Each playlist has the same five keys of the 'favorites'
and 'watchlater' dictionaries.
Each subdictionary has a key that is an alphanumeric string,
although this key doesn't really need to be used,
as we can just loop using `unpublished.values()`.
