來自外部文件的Python字典

Question

我想在Python中製作字典，但我不知道如何做兩件事。

1. 當我在字典中搜索關鍵字時，我不希望直接匹配，而是希望找到每個包含關鍵字的單詞。例如。搜索：貓 - 結果：貓，分配。

2. 我希望字典加載一個外部文件，因此我添加到字典中的新術語可以在以後加載時保存。

Answer 1

這應該讓你匹配貓在分配。

for key in dict.keys(): 
    if x in key: 
     do some stuff 

Answer 2

您可以使用下面的方法：
對於1

print ("Welcome back to the dictionary"); 

dict = {"CAT": "A small four legged animal that likes to eat mice", 
     "DOG": "A small four legged animal that likes to chase cats", 
     "ALLOCATE": "to give something to someone as ​their ​share of a ​total ​amount, to use in a ​particular way", 
     } 

def Dictionary(): 
    x = input("\n\nEnter a word: \n>>>"); 
    x = x.upper(); 
    found = False 
    for y in dict: 
     if x in y: 
      found = True 
      print (x,":",dict[x]) 
      Dictionary() 
      break 
    if not found: 
     y = input ("Unable to find word. Enter a new definition of your word: \n>>>"); 
     dict.update({x:y}) 
     Dictionary() 
Dictionary() 

爲2：您可以直接從JSON文件加載數據

import json 
dict = {} 
with open("test.json", "r") as config_file: 
    dict = json.load(config_file) 

其中test.json是你的文件爲例如
test.json

{"CAT": "A small four legged animal that likes to eat mice", 
     "DOG": "A small four legged animal that likes to chase cats", 
     "ALLOCATE": "to give something to someone as ​their ​share of a ​total ​amount, to use in a ​particular way", 
     }
