如何基于某些正则表达式拆分字符串？ （在python中）

Question

我有一个字符串是一堆句子，被“标题”：，“日期”：等等分开。

我想根据这些分隔符拆分此字符串。现在我有这个..

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)

输出：

{'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

您的输入是JSON，您可以使用json.loads()。

导入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'])
