I got it, changed it to:

    new_str = re.sub(r'[\w_+]', ' ', new_str)

Underscore is considered a "word character" in PCRE regular expressions. If what you want to match is "anything that is not a word character or an underscore", try this:

new_str = re.sub(r'[\W_]', ' ', new_str)

new_str = re.sub(r'[^\w]|_', ' ', new_str)

The underscore is part of the \w character group. Use this instead:

new_str = re.sub(r'[^a-zA-Z0-9]', ' ', new_str)

which is the same as \w but minus the underscore.
