集合没有 extend 方法,你可以用 |= 或者 update 来扩展集合,而且使用方法不要把小括号漏掉了:
f_suburbs = {"Randwick", "Kensington", "Frenchs Forest", "Flemington"}
f_suburbs.remove("Randwick")
f_suburbs.remove("Kensington")
f_suburbs |= {'Frenchs Forest', 'Flemington', 'Freshwater', 'Fairfield West', 'Five Dock', 'Fairfield Heights', 'Fairfield', 'Forest Lodge', 'Fairlight', 'Fairfield East', 'Freemans Reach', 'Forest Glen', 'Fiddletown', 'Forestville'}
print(f_suburbs)
或
f_suburbs = {"Randwick", "Kensington", "Frenchs Forest", "Flemington"}
f_suburbs.remove("Randwick")
f_suburbs.remove("Kensington")
f_suburbs.update({'Frenchs Forest', 'Flemington', 'Freshwater', 'Fairfield West', 'Five Dock', 'Fairfield Heights', 'Fairfield', 'Forest Lodge', 'Fairlight', 'Fairfield East', 'Freemans Reach', 'Forest Glen', 'Fiddletown', 'Forestville'})
print(f_suburbs)
