從字符串/文本文件創建字典

Question

我想組裝一個函數，該函數允許我從給定字符串甚至文本文件創建字典。

例如：

statement = "tell me what you want what you really really want" 

我想最終的結果看起來是這樣：

{tell: 1, me:1, what: 2, you: 2, want: 2, really: 2} 

字符串中的字符鍵，而它出現的次數是價值。

Answer 1

使用collections.Counter()，傳遞文字序列數：

>>> from collections import Counter 
>>> Counter('tell me what you want what you really really want'.split()) 
Counter({'you': 2, 'really': 2, 'what': 2, 'want': 2, 'tell': 1, 'me': 1}) 

Answer 2

沒有進口任何物件：從`collections`

statement = "tell me what you want what you really really want" 

end_result = dict() 

for word in statement.split(): 
    end_result[word] = end_result.get(word, 0) + 1
