Extract specific format from a string, regex, python

Question

DESCRIPTION:

I have a string with a word, a number, bracket, and a letter inside the bracket.

QUESTION:

I want to extract only the numbers with decimal and the bracket with a letter in it.

EXAMPLE:

, INC., 5.5(b) -------> 5.5(b)

Section 13.2(k)(ii) ---------> 13.2(k)(ii)

WBNEOGNOFD.)! 82.3(b)(k)(ix) -----------> 82.3(b)(k)(ix)

ATTEMPT I MADE:

Find the first number then the decimal, followed by '('. But, sometimes, its only 1 number and no brackets after the decimal.

SOLUTION I THINK WOULD SOLVE BUT I COULD NOT SOLVE IT:

curly brace repetition qualifiers {} to match exactly three alphabetic characters and exactly four numeric characters. I tried the answer given by Christian Dean to solve for my regex, but it did not give an accurate result. ( Extract string with specific format )

Answer 1

To match digits with decimals followed by groups of () s, you can use

\d+\.\d+(?:\(\w+\))+

• \\d+\\.\\d+ - Match a decimal number
• (?:\\(\\w+\\))+ - Repeat a group of word characters in parentheses
