How can I edit my normalize function so that it also removes punctuations and end of line characters

Question

How can I edit the normalize function so that it also removes the punctuations and end of line characters?

This is the code sample below:

    filename="bible.Sentences.15.txt"

    def getData(filename):

      with open(filename,'r') as f:

        #converting to list where each element is an individual line of text file

        lines=[line.rstrip() for line in f]

        return lines

    filename="bibleSentences.txt"

    getData(filename)

    

    def normalize(filename):

        #converting all letters to lowercase

        lowercase_lines=[x.lower() for x in getData(filename)]

        print(lowercase_lines)

        return lowercase_lines  

    normalize(filename)

Answer 1

Here is the solution code:

import re

...

def normalize(data):

    #converting all letters to lowercase

    lowercase_lines=[x.lower() for x in data]

    # strip out all non-word or tab or space characters

    stripped_lines = [re.sub(r"[^\w \t]+", "", x) for x in lowercase_lines]

    print(stripped_lines)

    return stripped_lines
