I am trying to extract the second match to "LOCATION \s+\S+" from the following text:

I am trying to get LOCATION 03-ED-0999-VAR (second match) from the text. Is there a way to specify that we want the second or the third or the nth match in python? Right now, I have the following code:

# imports
import os
import pandas as pd
import re
import docx2txt
import textract
import antiword

text = ' PAGE    1

location1 = re.search('LOCATION \s+\S+', text)

Answer 1

Instead of using re.search() you could try using re.findall() instead. This will get you all the matches in form of a list and you could pick whichever you'd like and even count how many you got.

location1 = re.findall("LOCATION \s+\S+", text)
print(len(location1)) # To print how many matches there are
print(location1[1]) # To print second match
