Help Fixing Code

[kianwalters05]

I'm doing a cybersecurity course and one of the levels requires editing a python script to brute force a .zip file. I edited some very easy errors like adding parenthesis etc. But when I run the code I get these errors and I dont know how to fix them.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40

import zipfile import itertools import time   # Function for extracting zip files to test if the password works! def extractFile(zip_file, password):     try:         zip_file.extractall(pwd=password)         return True     except KeyboardInterrupt:         exit(0) # Main code starts here... # The file name of the zip file. zipfilename = 'planz.zip' # The first part of the password. We know this for sure! first_half_password = 'Super' # We don't know what characters they add afterwards... # This is case sensitive! alphabet = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ' zip_file = zipfile.ZipFile(zipfilename)   # We know they always have 3 characters after Super... # For every possible combination of 3 letters from alphabet... for c in itertools.product(alphabet, repeat=3):     # Slowing it down on purpose to make it work better with the web terminal     # Remove at your peril     time.sleep(0.001)     # Add the three letters to the first half of the password.     password = first_half_password+''.join(c)     # Try to extract the file.     print ("Trying: %s"% password)     # If the file was extracted, you found the right password.     if extractFile(zip_file, password):         print ('*' * 20)         print ('Password found: %s' % password)         print ('Files extracted...')         exit(0)   # If no password was found by the end, let us know! print ('Password not found.')

Post your code here on the forum - in python tags, full traceback - in error tags.
See BBcode help for more info.

extractFile need pwd paramenter to be bytes not string.
Can do it in the function call.

1	if extractFile(zip_file, password.encode()):

The basic is.

1 2 3 4 5 6 7 8 9 10 11

>>> s = 'Secret' >>> s 'Secret' >>> type(s) <class 'str'> >>> >>> s_byte = s.encode() #Same as s.encode('utf-8') >>> s_byte b'Secret' >>> type(s_byte) <class 'bytes'>

Should i do it in a separate post or in a reply?
