RESULT:

Input one wowid (1 means WORLD_WOE_ID, 23424977 means US_WOE_ID, 0 to quit): 1  

Input another wowid (1 means WORLD_WOE_ID, 23424977 means US_WOE_ID, 0 to quit): 23424977
set([u'#NEDvsCRC', u'Happy 5th of July', u'#CostaRicavsHolanda', u'Tim Howard in Spanish', u'#GrantLandisDMMe'])  

Input one wowid (1 means WORLD_WOE_ID, 23424977 means US_WOE_ID, 0 to quit): 0<u>
