如何檢查文本文件中關鍵字的輸入？

Question

我想做一個程序，根據用戶輸入診斷計算機問題，並檢查關鍵字。我想要關鍵字在文本文件中。這是迄今爲止的代碼，但它從變量d中讀取關鍵字，而不是從文本文件中讀取。

d = {'screen': 'Get a new screen', ...} 
problem = input('What did you do? ').lower() 
for k in d: 
    if k in problem: 
     print(d[k])

您可以用JSON格式構造您的文本文件並使用python的json.load(your_file_name)。一個例子是：

# text file: diagnostics.json 
import json 

problems_db = {} # initialize this global variable with default value 
with open('diagnostics.json') as fp: 
    db_content = json.load(fp) 

problem = input('What did you do? ').lower() 
for k in problems_db: 
    if k in problem: 
     print(d[k]) 

實施例：

// diagnostics.json 
{ 
    "slow": "restart your computer", 
    "stuck": "restart your computer", 
    "not loading": "wait a few seconds, then restart your computer" 
} 

用戶交互：

"What did you do?" "my computer is really slow" 
"restart your computer"
