Assignment

[tinabina22]

This is an assignment that is due next week and I'm stuck on the for i in range code at the bottom highlighted with purple font.  I have included the instructions from my professor as well as the beginning of the code.  It's a password saver code that we need to make work.

Beginning of code:

import csv
import sys

#The password list - We start with it populated for testing purposes
passwords = [["yahoo","XqffoZeo"],["google","CoIushujSetu"]]


#The password file name to store the passwords to
passwordFileName = "samplePasswordFile"

#The encryption key for the caesar cypher
encryptionKey=16

#Caesar Cypher Encryption
def passwordEncrypt (unencryptedMessage, key):

  #We will start with an empty string as our encryptedMessage
  encryptedMessage = ''

  #For each symbol in the unencryptedMessage we will add an encrypted symbol into the encryptedMessage
  for symbol in unencryptedMessage:
      if symbol.isalpha():
          num = ord(symbol)
          num += key

          if symbol.isupper():
              if num > ord('Z'):
                  num -= 26
              elif num < ord('A'):
                  num += 26
          elif symbol.islower():
              if num > ord('z'):
                  num -= 26
              elif num < ord('a'):
                  num += 26

          encryptedMessage += chr(num)
      else:
          encryptedMessage += symbol

  return encryptedMessage

def loadPasswordFile(fileName):

  with open(fileName, newline='') as csvfile:
      passwordreader = csv.reader(csvfile)
      passwordList = list(passwordreader)

  return passwordList

def savePasswordFile(passwordList, fileName):

  with open(fileName, 'w+', newline='') as csvfile:
      passwordwriter = csv.writer(csvfile)
      passwordwriter.writerows(passwordList)

while True:
  print("What would you like to do:")
  print(" 1. Open password file")
  print(" 2. Lookup a password")
  print(" 3. Add a password")
  print(" 4. Save password file")
  print(" 5. Print the encrypted password list (for testing)")
  print(" 6. Quit program")
  print("Please enter a number (1-4)")
  choice = input()

  if(choice == '1'): #Load the password list from a file
      passwords = loadPasswordFile(passwordFileName)

  if(choice == '2'): #Lookup at password
      print("Which website do you want to lookup the password for?")
      for keyvalue in passwords:
          print(keyvalue[0])
      passwordToLookup = input()

What I need to make work:

for i in range(len('yahoo, google')):
  print('i')

#1. Create a loop that goes through each item in the password list
#  simplest way to loop through a list is: for i in range(len(NAMEOFLIST))
