How to remove punctuation in python?

Question

I've a problem:

E.x. I have a sentence

s = "AAA? BBB. CCC!" 

So, I do:

import string
table = str.maketrans('', '', string.punctuation)
s = [w.translate(table) for w in s]

And it's all right. My new sentence will be:

s = "AAA BBB CCC"

But, if I have input sentence like:

s = "AAA? BBB. CCC! DDD.EEE"

after remove punctuation the same method as below I'll have

s = "AAA BBB CCC DDDEEE"

but need:

s = "AAA BBB CCC DDD EEE"

Is any ideas/methods how to solve this problem?

Answer 1

string.punctuation contains following characters:

'!"#$%&\'()*+,-./:;<=>?@[\]^_`{|}~'

You can use translate and maketrans functions to map punctuations to empty values (replace)

import string

'AAA? BBB. CCC! DDD.EEE'.translate(str.maketrans('', '', string.punctuation))

Output:

'AAA BBB CCC DDDEEE'
