如何检查文本文件中关键字的输入？

Question

我正在尝试制作一个程序，该程序可以根据用户输入诊断计算机问题并检查关键字。我希望关键字位于文本文件中。这是我到目前为止的代码，但它从变量d 中读取关键字，而不是从文本文件中读取。

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

您可以以 JSON 格式构建文本文件并使用 python 的json.load(your_file_name)。一个例子是：

# 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])

例子：

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

用户交互：

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