I am having some difficulty with commenting my code for a python password cracking application, I have created. I have commented on the majority of the code however was wondering if anyone could suggest anymore comments I need as my instructor is really stick on me commenting my code.

Here is my code:

import time  import string  #Variables max_attempts = 999999999 #the number of attempts the system makes for a brute-force attack start       = time.time() #monitors the time length chars       = list(string.printable) #all the possible ascii characters which the system uses to determine the password base        = len(chars) #the base for conversion n           = 0 #number of attempts solved      = False password    = input("Enter your password:") #the feature which allows the user to enter in their chosen password  print(chars) #record of previous password attempts  # converts number N base 10 to a list of digits base b def numberToBase(n, b):     digits = []     while n: # takes n and the finds the modulus, the remainder of n % b         digits.append(int(n % b)) # then it will append that to a list         n //= b # following on it will then divide n into b     return digits[::-1] #returns those digits into reverse order from -1, the end to the beginning   # checks if the user has inputted empty text/numbers/symbols if password == '':      print('Your password is empty')     solved = True  elif password == chars[n]:     print('Your password is ' + chars[n])     solved = True  else:     n = 1  #Begins systematically checking the password if not solved:     while n < max_attempts:         list = numberToBase(n, base)         print(list)         word = ''         for c in list: #loop through each of the characters in the list             word += str(chars[c]) #adds the characters from the list to a word         print(word)         if password == word: #checks if the password equals to the word the system has generated             solved = True # if the generation is correct the password will then commence to print statements             print('***Results***')             print('Password: ' + word)             print('Attempts: ' + str(n))             print('Time: ' + str((time.time() - start)) + ' sec')              break #stops the loop         else:             n += 1 #however if the password generation isn't correct, we increment with n  # the password is beyond max_attempts if not solved:     print('Unsolved after ' + str(n) + ' attempts!')
