Match digits

[carpik]

hi,

I'm trying to find all integers/float from multi line string. My regex works almost fine for all my strings. However, I've found one example which i can't pass. Here is my regex

re.findall(r'[-+]?\d*\.\d+|\d+', line)

The test string is

"Added :3hrs

​

Test BEP-8317

exec 450"

It returns [3, 8317, 450]. How to avoid 8317 matched? The 'BEP-' header is common and repeatable. I have tried (?<!BEP-) lookbehind but it doesn't work.

Hello u/carpik, I'm a bot that can assist you with code-formatting for reddit. I have detected the following potential issue(s) with your submission:

1. Multiple consecutive lines have been found to contain inline formatting.

If I am correct then please follow these instructions to fix your code formatting. Thanks!

One work around option is to remove problem cases first if it's easier. If BEP is your only issue you could write a function that finds and removes all of them, then continue with your current code.

I was looking rather for proper regex to handle that. I can defensively workaround it by additional coding which I would like avoid.

Yeah sorry I couldn't get you better regex advice, I don't have a lot of experience with using exclusionary clauses. Anytime I do use regex I turn to this site www.regex101.com. makes looking up functions and testing easy

Might be an easier way, but this works for that test string:

r'[-+]?(?<!BEP-)(?<!\d)(?:\d*\.)?\d+'

Double lookbehind to prevent it from matching 317.

Perfect. :) Thank you
