I'm trying to split a string in a list of strings. Right now i have to split whenever I see any of these characters: '.', ';', ':', '?', '!', '( )', '[ ]', '{ }' (keep in mind that I have to mantain whatever is inside the brackets). To solve it I tried to write

print(re.split("\(([^)]*)\)|[.,;:?!]\s*", "Hello world,this is(example)"))

but as output I get:

['Hello world', None, 'this is', 'example', '']

Omitting the ' ' at the end that I'll solve later, how can I remove the None that appears in the middle of the list? By the way I can't iterate in the list another time because the program shall work with huge files and I have to make it as fast as possible. Also I don't have to necessarily use re.split so everything that works will be just fine!

I'm still new at this so I'm sorry if something is incorrect.

Not sure if this is fast enough but you could do this:

re.sub(r";|,|:|\(|\)|\[|\]|\?|\.|\{|\}|!", " ", "Hello world,this is(example)").split()
