Hi Joe, I hope that this ok to submit an
I recommend adding a read option from a file of the subdomains array with the function readfile, It will be much more convenient best regards Bin

try: domain = sys.argv[1] except IndexError: print('Syntax Error - python3 subdomenum.py ')

Using readlines()

file1 = open('path to file', 'r') subdomain_array = file1.readlines()

def main(): subdomain_store = [] for subdoms in subdomain_array: try: subdoms = subdoms.strip() ip_value = dns.resolver.resolve(f'{subdoms}.{domain}', 'A') if ip_value: subdomain_store.append(f'{subdoms}.{domain}') if f"{subdoms}.{domain}" in subdomain_store: print(f'{subdoms}.{domain} valid') else: pass except dns.resolver.NXDOMAIN: pass except dns.resolver.NoAnswer: pass except KeyboardInterrupt: quit()

main()

hello I loved your youtube video it was super clear and informative but I wanted to implement it in a REST API so how can I convert this output into a JSON output?
