Regex uppercase words with condition

Question

I'm new to regex and I can't figure it out how to do this:

Hello this is JURASSIC WORLD shut up Ok

[REVIEW] The movie BATMAN is awesome lol

What I need is the title of the movie. It will be only one per sentence. I have to ignore the words between [] as it will not be the title of the movie.

I thought of this:

^\w([A-Z]{2,})+

Any help would be welcome.

Thanks.

Answer 1

You can use negative look arounds to ensure that the title is not within []

\b(?<!\[)[A-Z ]{2,}(?!\])\b

• \\b Matches word boundary.

• (?<!\\[) Negative look behind. Checks if the matched string is not preceded by [

• [AZ ]{2,} Matches 2 or more uppercase letters.

• (?!\\]) Negative look ahead. Ensures that the string is not followed by ]

Example

>>> string = """Hello this is JURASSIC WORLD shut up Ok
... [REVIEW] The movie BATMAN is awesome lol"""
>>> re.findall(r'\b(?<!\[)[A-Z ]{2,}(?!\])\b', string)
[' JURASSIC WORLD ', ' BATMAN ']
>>>
