Using the OR (|) function in regex

So I am using a Regular Expressions to extract all areas from a document. The problem is the areas are sometimes expressed with m2 and sometimes with m². I thought I can solve this problem by using the OR (|) operator like this

(\d+.\d+|\d+.\d+?\s)m(2|²)

but when I use this regex with the findall function he returns this for example:

('7,96 m2', '7,96 ', '2')

The desired output is of course:

('7,96 m2')

Am I using the brackets wrong?

Use non-capturing groups or `re.finditer` to get the `match.group()` values. Besides, you can fix your regex, `\d+(?:[.,]\d+)?\s?m[2²]` – Wiktor Stribiżew May 23 '20 at 08:42
modifying regex pattern seems to work, try ```re.findall("\d+,\d+\sm\d", "7,96 m2")``` – sushanth May 23 '20 at 08:46
