checking to see if a database is empty

I want to create an option to delete a record in Sqlite, but I need to know if the database is empty. If it is empty then it gets stuck in the loop asking which record I want to delete. I tried

game_player = Player.select()
if game_player == None:
     print('no players found')

and did the requisite coding to get out of the loop. I suspect this is wrong. Any advice?

Figured it out!!! To the people of the future, near and far:

game_players  =  Player.select()
if game_players.count() == 0:
    do the thing
else:
    do the other thing

count() gets the amount of records in the database.
