python dict.keys（）不返回所有值

Question

我是python編程新手。我正在嘗試製作一個程序，作爲天際藥水效果的互動詞典，以便練習拼寫檢查功能。

這是我的代碼的相關位。

effectslist = effects.keys() 
print (effectslist) 

麻煩的是，effectslist將不包含字典中的作用的所有鍵。我不清楚它是否一直放棄相同的鍵或循環列表，但我需要它創建一個用作特效字典中鍵的字符串的完整列表。

任何人都可以向我解釋爲什麼它沒有列出完整的列表，我可以做些什麼來創建完整列表？

謝謝

Answer 1

麻煩的是，effectslist將不包含字典中的作用的所有鍵。

其實沒有。它包含所有的鍵。

首先，keys()返回正確數量的元素：

>>> len(effects) 
44 
>>> len(effects.keys()) 
44 

其次，所有的元素，它返回是唯一的：

>>> len(set(effects.keys())) 
44 

最後，每次返回鍵出現在詞典：

>>> all(k in effects for k in effects.keys()) 
True 

如果您要嘗試找到一個特定的密鑰，不是由.keys()返回，我相信你會發現沒有一個。

Answer 2

我自己運行了代碼，看起來len(effects)==len(effectslist)，所以所有帳戶都返回完整列表。是什麼讓你覺得它沒有返回完整列表？請記住，詞典不以固定順序存在 - 因此，當您查詢密鑰時，它們將不會與您輸入的順序相同。
