people =
lloyd = people
alice = people
tyler = people
lloyd['name'] = "lloyd"
alice['name'] = "alice"
tyler['name'] = "tyler"
print lloyd
這個來自codecademy的一段教學...(當然整個**都是我自己敲的..)
然而這樣寫的結果是lloyd people等等都是乙個變數..= =
如果要達到目標效果 那麼要寫成這樣
people =
lloyd = people.copy()
alice = people.copy()
tyler = people.copy()
lloyd['name'] = "lloyd"
alice['name'] = "alice"
tyler['name'] = "tyler"
print lloyd
其中這裡的關鍵是 python裡的例項名往往指的都是類似於c++的引用
順手發乙個很好玩的東西~（當然這個可以認為是原創或者非原創啦...）
