Python Regex 从字符串中提取位置和时间戳

Question

I am a complete newbie to Python and after any help possible. Below is sample text string which I am trying to extract 2 substrings:

1. Location
2. Timestamp

Sample text: Your booking at Crown Street - June 29th, 1:00pm

The Location substring is between the following 2 phrases were are constant "Your booking at " and " -". The spaces includes in the phrases are deliberate. In this example, my required output string is Crown Street . What is the best Python regex to deliver this outcome?

The Timestamp substring procedes "- " expression in the string. In this example, my required output string is June 29th, 1:00pm . What is the best Python regex to deliver this outcome?

Answer 1

import re

example = 'Your booking at Crown Street - June 29th, 1:00pm'
regex = re.compile(r'Your booking at (?P<location>.+) - (?P<timestamp>.+)$')
print(regex.match(example).groupdict())

outputs

{'location': 'Crown Street', 'timestamp': 'June 29th, 1:00pm'}

Notice that this could end up in a false match if there's a - in the name of the location; if you're always sure there'll be an English month to start the timestamp, you could use (?P<timestamp>(?:Jan|Feb|Mar|...).+) .

Answer 2

Using re.search

Demo:

import re
text = "Your booking at Crown Street - June 29th, 1:00pm"

data = re.search("Your booking at\s+(.*)\s+\-\s+(.*)", text)
if data:
    print(data.group(1))
    print(data.group(2))

Output:

Crown Street
June 29th, 1:00pm
