Below code is not working without any output

My code is :

import re
log_file_path = 'C:\\Users\\kkk.txt'
def extract_user_and_machine(log_file_path):
# Regular expression to match 'user <username> by machine <machine>'
pattern = r'user (\S+) by machine (\S+)'

with open(log_file_path, 'r') as log_file:
log_lines = log_file.readlines()

# List to hold extracted 'user@machine' combinations
user_machine_combinations = []

for line in log_lines:
# Search for the pattern in each line
match = re.search(pattern, line)
if match:
# Extract username and machine, then combine them in 'user@machine' format
username = match.group(1)
machine = match.group(2)
user_machine_combinations.append(f"{username}@{machine}")

# Display the results
if user_machine_combinations:
print("User@Machine combinations found in the log file:")
for combination in user_machine_combinations:
print(combination)
else:
print("No user-machine combinations found in the log file.")
