I have a python project that requires me to make a password saver. The major part of the code is already giving. I am having trouble executing option 2 and 3. Some guidance will be appreciated. Below is the code giving to me.

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() ####### YOUR CODE HERE ###### #You will need to find the password that matches the website #You will then need to decrypt the password # #1. Create a loop that goes through each item in the password list # You can consult the reading on lists in Week 5 for ways to loop through a list # #2. Check if the name is found. To index a list of lists you use 2 square backet sets # So passwords[0][1] would mean for the first item in the list get it's 2nd item (remember, lists start at 0) # So this would be 'XqffoZeo' in the password list given what is predefined at the top of the page. # If you created a loop using the syntax described in step 1, then i is your 'iterator' in the list so you # will want to use i in your first set of brackets. # #3. If the name is found then decrypt it. Decrypting is that exact reverse operation from encrypting. Take a look at the # caesar cypher lecture as a reference. You do not need to write your own decryption function, you can reuse passwordEncrypt # # Write the above one step at a time. By this I mean, write step 1... but in your loop print out every item in the list # for testing purposes. Then write step 2, and print out the password but not decrypted. Then write step 3. This way # you can test easily along the way. # ####### YOUR CODE HERE ###### if(choice == '3'): print("What website is this password for?") website = input() print("What is the password?") unencryptedPassword = input() ####### YOUR CODE HERE ###### #You will need to encrypt the password and store it in the list of passwords #The encryption function is already written for you #Step 1: You can say encryptedPassword = passwordEncrypt(unencryptedPassword,encryptionKey)] #the encryptionKey variable is defined already as 16, don't change this #Step 2: create a list of size 2, first item the website name and the second item the password. #Step 3: append the list from Step 2 to the password list ####### YOUR CODE HERE ###### if(choice == '4'): #Save the passwords to a file savePasswordFile(passwords,passwordFileName) if(choice == '5'): #print out the password list for keyvalue in passwords: print(', '.join(keyvalue)) if(choice == '6'): #quit our program sys.exit() print() print()
