My Python Regex Expression is not working properly in my code-CodePudding

I have this regex expression that work on regex101. But in my python code, it is returning None. If you guys can help me out that would be great.

Link to my regex expression https://regex101.com/r/T0Jvq4/1

This is my function.

legalDescription = tryRegexData(r"(?<=Legal Description:)(\n)(.*)^(?:(?!Property Use:).)*",propertyArea,0)

def tryRegexData(regex,area,num):

  try: 
      return re.search(regex,area.text).group(num).strip()
  except Exception as e:
      return ""

Thank you

CodePudding user response：

I would suggest simplifying your pattern and just use dot all mode:

def tryRegexData(area):

  try: 
      return re.search(r'\bLegal Description:\s (.*?)\s Property Use:', area.text, flags=re.S).group(1)
  except Exception as e:
      return ""

You can simplify your rexpression to r"(?<=Legal Description:\n)(.*)(?=\nProperty Use:)"

import re

str = """General Info

rgx  = r"(?<=Legal Description:\n)(.*)(?=\nProperty Use:)"

lst = re.findall(rgx, str)

print(lst[0])
# 'AREA THAT I WANT TO CAPTURE'
