Editing a txt file in Python to edit the formatting and then create new txt file

Question

and thank you for taking the time to read this post. This is literally my first time trying to use Python so bare with me.

My Target／Goal: Edit the original text file (Original .txt file) so that for every domain listed an "OR" is added in between them (below target formatting image). Any help is greatly appreciated.

I have been able to google the information to open and read the txt file, however, I am not sure how to do the formatting part.

Script

Original .txt file

Target formatting

Answer 1

You can achieve this in a couple lines as:

with open(my_file) as fd:
    result = fd.read().replace("n", " OR ")

You could then write this to another file with:

with open(formatted_file, "w") as fd:
     fd.write(result)

something you could do is the following

import re


# This opens the file in read mode
with open('Original.txt', 'r') as file:
    # Read the contents of the file
    contents = file.read()

# Seems that your original file has line breaks to each domain so
# you could replace it with the word "OR" using a regular expression
contents = re.sub(r'n+', ' OR ', contents)

# Then you should open the file in write mode
with open('Original.txt', 'w') as file:
    # and finally write the modified contents to the file
    file.write(contents)

a suggestion is, maybe you want to try first writing in a different file to see if you are happy with the results (or do a copy of Original.txt just in case)


with open('AnotherOriginal.txt', 'w') as file:
    file.write(contents)
