Python Comparing Text File - If Else Printing

I have 4 text files in the following formats keycountry.txt UK USA Germany country.txt Brexit - UK USA UK Relations France win world cup keylink.txt www.abc.com www.ddd.com www.e

Solution 1:

Seems like your issue is on one hand related with the for-else construct. Else will always get executed in your code.

Moreover, building upon kaihami's answer, to achieve what you are describing you need to store the matching links/lines in a separate structure like a list and then check if that list is empty to print the matched entries or the string "Not matching", here is my proposed solution:

import re

keycountryfile = "keycountry.txt"
countryfile = "country.txt"withopen('links.txt', 'r') as links:
    links_data = [line.strip() for line in links.readlines()]

withopen('keylink.txt', 'r') as keys:
    keys_links = set([line.strip() for line in keys.readlines()])


matching_links = []
for url in links_data:
    if url in keys_links:
        matching_links.append(url)

print('LINKS')
if matching_links:
    print('\n'.join(matching_links))
    print("matching")
else:
    print("Not matching") 

print()

withopen(keycountryfile , "r") as f:
    country_keys = set(key.lower() for key in 
                       re.findall(r'\w+', f.readline()))

matching_lines = []
withopen(countryfile) as f:
    for line in f:
        words = set(word.lower() for word in re.findall(r'\w+', line))
        if country_keys & words:
            matching_lines.append(line.strip())
    print("COUNTRY")
    if matching_lines:
        print('\n'.join(matching_lines))
        print("matching")
    else:            
        print("Not matching")

Solution 2:

You can save your results to a list and print the results after finding all matches.

import re

keycountryfile = '''UK USA Germany'''
countryfile = '''Brexit - UK
USA UK Relations
France win world cup'''

links = '''www.abc.com
www.eee.com'''

links_data = links.split()

keys = '''www.abc.com
www.ddd.com
www.eee.com'''
keys_data = keys.split()


keys_split = keys_data

matching_links = []
not_links = []
for url in keys_split:
    if url in links_data:
        matching_links.append(url)
    else:
        not_links.append(url)

keys = set(keycountryfile.split())

matching_country = []
not_country = []
for line in countryfile.split():
    words = set(word.lower() for word in re.findall(r'\w+', line))
    if keys & words:
        matching_country.append(line)
    else:
        not_country.append(line)

print('LINKS')
if matching_links:
    print('\n'.join(matching_links))
    print("matching")

print("COUNTRY")
print()
if matching_country:
    print('\n'.join(matching_country))
    print("matching")

print('LINKS')
if not_links:
    print('\n'.join(not_links))
print("Not matching")

print("COUNTRY")
if not_country:
    print('\n'.join(not_country))
print("Not matching")
