How do I remove patterns in text file?

I would like to remove patterns within in a text file (no_war_sc_r.txt). The .txt file holds mutliple articles that have word patterns I would like to remove.

I imported the 're' package that I found helps with this.

This is the code:

But, when I ran the code it gave me this error:

import re

rgx_list = ['Read More',
'Read',
'And follow us on Twitter to keep up with the latest news and and acute and primary Care.', …]

new_text = open('/Users/sofia/Documents/src/fakenews1/data/news-data/no_war_pc_r_sophia.txt')

for rgx_match in rgx_list:
new_text = re.sub(rgx_match, '', new_text)

print(new_text)

This is because open() only creates and returns a file object, not a string. You can read the from the file using its read() method. Calling new_text.read() without any arguments will return a string containing the entire text of the file.

open()

read()

new_text.read()

Also, it is better to a context manager to interact with files,

txt_path = '/Users/sofia/Documents/src/fakenews1/data/news-data/no_war_pc_r_sophia.txt'

with open(txt_path) as new_txt_file:
new_text = new_txt_file.read()
