# Removing text inside brackets [closed]

The following function removes text inside parenthesis, also checks for balanced brackets. Example: RemoveTextInsideParenthesis('Yahoo (Inc)') will return 'Yahoo' Any suggestions in how to improve readability/simplify it?

def RemoveTextInsideParenthesis(text: str) -> str:
"""Remove text inside brackets or nested brackets.

Creates an array: ['(',')'...], then for each character in text string
we compare if character is a bracket, if it is we update a status array.
Based on status array we can evaluate if brackets are open and close correctly
and then capture text outside parenthesis.
Using divmod function we extract index of brackets array.
Take two (non complex) numbers as arguments and return a pair of numbers
consisting of their quotient and remainder.
Documentation for brackets:

Args:
text: Text to be clean up.

Returns:
Text inside parenthesis

• Could you give a few more examples of what the function needs to do? I'm not really understanding the idea behind... – RandomDude Jul 25 '18 at 7:06
• Also can you give more details about the constraints you are trying to implement? You say that the code check for balanced brackets but 'This is [a test { and a simple] one}. Isn\'t it?' is shortened to 'This is . Isn\'t it?'; this doesn't feel like any balancing is at play, only that the first opener is matched to the last closer… I would have expected something like 'This is one}. Isn\'t it?' instead or at least 'This is [a test . Isn\'t it?'. – 301_Moved_Permanently Jul 25 '18 at 7:57
• I'm looking for a way to improve readability, I needed to add many comments for my colleagues to understand the algorithm, probably a simpler way to do it? – gogasca Jul 25 '18 at 17:21
