In your Python code (nettacker.py), consider adding more command examples. This helps new users who may find it difficult to create the right commands when they use your code for the first time. It makes it easier for them to write the correct code.

Like that:-

nettacker -L en -v -o results.txt -i target.com -m ftp_brute,ssh_brute -u admin -P passwords.txt -g 21,22 --start-api --api-host 0.0.0.0 --api-port 5000
