使用详细输出进行错误处理

Question

Im trying to implement the --verbose option in my script. The idea is to turn on extra printing of errors etc for debugging, but for some reason it doesnt seem to work. Ive tried a few variations of the if verbose statement but no joy. Im hoping someone could point me in the right direction?

CLI EXAMPLE

./attack2.py -f wordfile.txt -d google.com --verbose 1

CLI OUTPUT

unknown@ubuntu:~$ ./attack2.py -f wordfile.txt -d google.com --verbose 1
173.194.34.149
173.194.34.130
unknown@ubuntu:~$

ARG PRINT

{'--domain': 'google.com',
 '--file': 'wordfile.txt',
 '--help': False,
 '--thread': False,
 '--verbose': True,
 '10': False,
 '<1>': '1'}

CODE

#!/usr/bin/python

        returned_list = fread(arguments['--file'])
        returned_domains = subcheck(returned_list, arguments['--domain'], ['--verbose'])

Answer 1

The below line in function subcheck

returned_domains = subcheck(returned_list, arguments['--domain'], ['--verbose'])

should be

returned_domains = subcheck(returned_list, arguments['--domain'], arguments['--verbose'])

You forgot to pass the verbose param from arguments, instead you passed a list

Answer 2

It seems I was calling the subcheck incorrectly.

Code should have looked like this

Working CODE

if __name__ == "__main__":
        arguments = docopt(__doc__, version='0.1a')

        fread(arguments['--file'])
        returned_list = fread(arguments['--file'])
        returned_domains = subcheck(returned_list, arguments['--domain'], arguments['--verbose'])
        print returned_domains
