Python-在其他两个特定字符之间的字符串中提取文本？

Question

I have various strings of text that have a user's name, their business name and phone number and they are all similar to the following:

FirstName LastName (Some Business Name / phoneNumber)
FirstName LastName (Business Name / phoneNumber)
FirstName LastName (BusinessName / differentphoneNumber)
FirstName LastName (Short Name / somephoneNumber)
FirstName LastName (Very Long Business Name / otherphoneNumber)

Real world examples could look like this:

David Smith (Best Pool and Spa Supplies / 07438473784)
Bessy McCarthur Jone (Dog Supplies / 0438-343522)

I have used this code to extract the first name (as I needed this earlier) and it works well:

import re
details = re.findall(r'^[\w+]+', input_data['stripeDescription'])
return {
'firstName': details[0] if details else None\``
}

How can I go about finding the text between the open bracket "(" and the forward slash "/" to then retrieve the business name?

Answer 1

This may not be a perfect solution but it works fine :)

s1='David Smith (Best Pool and Spa Supplies / 07438473784)'
sp1=s1.split('(')
sp2=sp1[1].split('/')
print(sp2)

output: ['Best Pool and Spa Supplies ', ' 07438473784)']

Answer 2

Use parentheses to group the pattern you want to match in the regex you use for re.findall :

s = '''David Smith (Best Pool and Spa Supplies / 07438473784)
Bessy McCarthur Jone (Dog Supplies / 0438-343522)'''
import re
print(re.findall(r'\(([^/]+?) */', s))

This outputs:

['Best Pool and Spa Supplies', 'Dog Supplies']

Answer 3

This is fairly robust, but will not handle a name with parentheses in it. ie it expects the first ( to delimit past the name. However, you might be able know something is wrong by noting that the business then has \\).*\\( in it.

data = """
David Smith (Best Pool and Spa Supplies / 07438473784)
David Smith2 (Best Pool/Spa Supplies / 07438473784)
Bessy McCarthur Jone (Dog Supplies / 0438-343522)
Bessy McCarthur Jone2 (Dog (and cat) Supplies / 0438-343522)
Bessy (Bess, fails) McCarthur Jone3 (Dog Supplies / 0438-343522)
"""

lines = [line.strip() for line in data.splitlines() if line.strip()]

for line in lines:
    name,rest = line.split("(",1)
    name = name.strip()
    phone = rest.rsplit("/")[1].replace(")","").strip()
    biz = rest.rsplit("/",1)[0].strip()
    print("\n "+line)
    print(" =>name:%s: phone:%s:biz:%s:" % (name, phone,biz))

output:

 David Smith (Best Pool and Spa Supplies / 07438473784)
 =>name:David Smith: phone:07438473784:biz:Best Pool and Spa Supplies:

 David Smith2 (Best Pool/Spa Supplies / 07438473784)
