How do you append the same text to multiple txt files in python?

Question

Imagine you have some text that you want to split into chunks and send to separate files which are named using l’mahdi’s solution found here

But imagine there is a header at the top of the file:

company:: acme products
department:: sales
floor:: 1

name:: Joe Blogs 
phone:: 123456789
email:: [email protected]
address:: 123 Main Street
note:: blah blah blah
timestamp::

name:: Josephine Blogs 
phone:: 43217890
email:: [email protected]
address:: 123 Main Street
note:: More blah blah
timestamp::

name:: John Smith 
phone:: 23498689
email:: [email protected]
address:: 1 North Street
note:: Some more blah
timestamp::

How do you append the header to each file so we get the following files?

# chunk_1.txt
name:: Joe Blogs 
phone:: 123456789
email:: [email protected]
address:: 123 Main Street
note:: blah blah blah
timestamp:: 2022-07-15 (15h 12m 25s)
company:: acme products
department:: sales
floor:: 1


# chunk_2.txt
name:: Josephine Blogs 
phone:: 43217890
email:: [email protected]
address:: 123 Main Street
note:: More blah blah
timestamp:: 2022-07-15 (15h 12m 26s)
company:: acme products
department:: sales
floor:: 1


# chunk_3.txt
name:: John Smith 
phone:: 23498689
email:: [email protected]
address:: 1 North Street
note:: Some more blah
timestamp:: 2022-07-15 (15h 12m 27s)
company:: acme products
department:: sales
floor:: 1

Just split the header firstly, you can try my solution:

from datetime import datetime
import time
import re

with open('file.txt') as f:
    header, content = f.read().split('nn', maxsplit=1)
    for n, chunk in enumerate(content.split('nn'), start=1):
        timestamp = datetime.now().strftime('%Y-%m-%d (%Hh %Mm %Ss)')
        chunk = re.sub(r'(timestamp::)', fr'1 {timestamp}', chunk)
        chunk = chunk.strip() + 'n' + header
        with open(f'chunk_{n}.txt', 'w') as f_out:
            f_out.write(chunk)
        time.sleep(1)

And here is the result:

# chunk_1.txt

name:: Joe Blogs
phone:: 123456789
email:: [email protected]
address:: 123 Main Street
note:: blah blah blah
timestamp:: 2022-08-07 (13h 10m 08s)
company:: acme products
department:: sales
floor:: 1

# chunk_2.txt

name:: Josephine Blogs
phone:: 43217890
email:: [email protected]
address:: 123 Main Street
note:: More blah blah
timestamp:: 2022-08-07 (13h 10m 09s)
company:: acme products
department:: sales
floor:: 1

# chunk_3.txt

name:: John Smith
phone:: 23498689
email:: [email protected]
address:: 1 North Street
note:: Some more blah
timestamp:: 2022-08-07 (13h 10m 10s)
company:: acme products
department:: sales
floor:: 1
