Question

I want to replace the word "example" on textfile2.txt with a list of words from textfile1.txt until the list runs out or all the "example" have all been replaced then I want to display the whole finished text.

How would I do this?

textfile1.txt

user1
user2

textfile2.txt

URL GOTO=https://www.url.com/example
TAG POS=1 TYPE=BUTTON ATTR=TXT:Follow

URL GOTO=https://www.url.com/example
TAG POS=1 TYPE=BUTTON ATTR=TXT:Follow

Current code:

with open('textfile1.txt') as f1, open('textfile2.txt') as f2:
    for l, r in zip(f1, f2):
        print(r[:r.find('/example') + 1] + l)

Results it gives me:

URL GOTO=https://www.instagram.com/user1

user2

Goal:

URL GOTO=https://www.url.com/user1
TAG POS=1 TYPE=BUTTON ATTR=TXT:Follow

URL GOTO=https://www.url.com/user2
TAG POS=1 TYPE=BUTTON ATTR=TXT:Follow

Answer 1

here is the my solution:

with open('t1.txt') as f1, open('t2.txt') as f2:
    url_info = f2.read().split('\n\n')
    users = f1.read().split('\n')
    zipped_list = zip(users, url_info)
    for item in zipped_list:
        print item[1].replace('example', item[0])+"\n"

updated: this need import itertools

import itertools
with open('t1.txt') as f1, open('t2.txt') as f2:
    url_info = f2.read().split('\n\n')
    users = [u for u in f1.read().split('\n') if u]
    zipped_list = list(itertools.izip(url_info, itertools.cycle(users)))    
    for item in zipped_list:        
        print item[0].replace('example', item[1])+"\n" 

output:

URL GOTO=https://www.url.com/user1
TAG POS=1 TYPE=BUTTON ATTR=TXT:Follow

URL GOTO=https://www.url.com/user2
TAG POS=1 TYPE=BUTTON ATTR=TXT:Follow

URL GOTO=https://www.url.com/user1
TAG POS=1 TYPE=BUTTON ATTR=TXT:Follow
