Python文本抽取到字典

Question

我是个新手，谁能帮我用正则表达式或任何其他技术将下面的文本集转换成字典

Bus Number: Departure，将在所有消息/块中通用

KPN_Sleeper: Bus Number: Departure 
Bus code: Kpn-866489 KA-01-7233 Bangalore 
AC Sleeper/56 Seats
24 Seats booked 

SRS: Bus Number: Departure 
Bus code: SRS-5858 KA-31-5985 Bangalore 


SAM: Bus Number: Departure 
Bus code: SAM-0077 TN-23-0777 Chennai 

{0:{
  "Bus_name": "KPN_Sleeper",
  "Bus code":"Kpn-866489",
  "Bus Number": "KA-01-7233",
  "Departure": "Bangalore",
  "others": "AC Sleeper/56 Seats 24 Seats booked "
},
1:{
  "Bus_name": "SRS",
  "Bus code":"SRS-5858",
  "Bus Number": "KA-31-5985",
  "Departure": "Bangalore",
  "others": ""
}}

因为我对编码和正则表达式还不熟悉，所以我觉得很难构造

Answer 1

根据您的意见，我认为您可以尝试以下方法：

^(.*):\s*Bus Number: Departure\s*\nBus code:\s*([^ ]+)\s([^ ]+)\s([^\n]+)[ \t]*(?:\n|$)((?:[^\n]+(?:\n|$))+)?

Regex Demo

示例代码（run here）：

regex = r"^(.*):\s*Bus Number: Departure\s*\nBus code:\s*([^ ]+)\s([^ ]+)\s([^\n]+)[ \t]*(?:\n|$)((?:[^\n]+(?:\n|$))+)?"

test_str = ("KPN_Sleeper: Bus Number: Departure \n"
    "Bus code: Kpn-866489 KA-01-7233 Bangalore dfdf\n"
    "AC Sleeper/56 Seats\n"
    "24 Seats booked \n\n"
    "SRS: Bus Number: Departure \n"
    "Bus code: SRS-5858 KA-31-5985 Bangalore dfdf dfd\n\n\n"
    "SAM: Bus Number: Departure \n"
    "Bus code: SAM-0077 TN-23-0777 Chennai \n"
    "asdfadf ;kasdjlfads;f lkadsjf")

matches = re.finditer(regex, test_str, re.MULTILINE)


for match in matches:
    print("Bus Name: "+match.group(1)+"Bus Code: "+match.group(2)+" Bus No: "+match.group(3)+" Departure: "+match.group(4))


#you can have other's value in match.group(5) , however, having it is conditional

说明：

1. ^(.*):\s* (.*)>；第一个捕获组以获取总线名称\s*以覆盖空白

2. Bus Number: Departure\s*\n>；公共汽车号码：出发，然后是空格和换行

3. Bus code:\s*下一行以总线代码冒号和选项空格开始

4. ([^ ]+)\s([^ ]+)\s([^\n]+)[ \t]*

   a）{}>；总线代码\s>；空白处

   b）{}>；总线号\s>；空白处

   c）{}>；离开，它可能有多个单词

   d）[ \t]*>；它覆盖了起飞后的尾随空间

5. (?:\n|$)>；它覆盖了换行符或字符串的结尾

6. ((?:[^\n]+(?:\n|$))+)?

   a）{}>；匹配除换行符后跟换行符或字符串结尾以外的任何内容

   b）?:使其成为非捕获组

   c）+表示可以有多行

   d）最后的()对组中的所有other行求和

   e）?使整个other过程成为可选过程
