如何基於某些正則表達式拆分字符串？ （在python中）

Question

我有一個字符串，它是一堆句子，由“ title”：，“ date”：等分隔。

我想根據那些定界符來分割此字符串。 現在我有這個..

line =  re.split(r'("[a-z]: ")', line)



  {"date": "Jul 18, 2017, 4:10 AM", 
    "text": "Best / cheapest", 
    "state_or_country_or_utility": "Norway Travel Forum", 
    "responses": ["The local train www.nsb.no"],
    "title": "airport transfer "}

Answer 1

您可以使用ast.literal_eval ：

import ast
s = '{"date": "Jul 18, 2017, 4:10 AM", "text": "Best / cheapest", "state_or_country_or_utility": "Norway Travel Forum", "responses": ["The local train www.nsb.no"], "title": "airport transfer "}'
final_data = ast.literal_eval(s)

輸出：

{'date': 'Jul 18, 2017, 4:10 AM', 'text': 'Best / cheapest', 'state_or_country_or_utility': 'Norway Travel Forum', 'responses': ['The local train www.nsb.no'], 'title': 'airport transfer '}

Answer 2

您輸入的是JSON，可以使用json.loads() 。

導入json

data = '''{"date": "Jul 18, 2017, 4:10 AM", 
    "text": "Best / cheapest", 
    "state_or_country_or_utility": "Norway Travel Forum", 
    "responses": ["The local train www.nsb.no"],
    "title": "airport transfer "}'''

result = json.loads(data)
print('Title = ', result['title'])
print('Date = ', result['date'])
