Here is the error:
Traceback (most recent call last):
File "D:\Python24\password.py", line 91, in -toplevel-
save_file(sitelist)
File "D:\Python24\password.py", line 22, in save_file
for site,ID,passcard in sitelist.items():
ValueError: need more than 2 values to unpack
Here is the code:
#This is for a password protected program to store passwords.
import getpass
password = "hello"
sitelist = {}
def load_file(pw):
import os
filename = 'passcard.txt'
if os.path.exists(filename):
store = open(filename,'r')
for line in store:
site = line.strip()
ID = line.strip()
passcard = store.next().strip()
pw[site] = ID and passcard
else:
store = open(filename,'w') # create new empty file
store.close()
def save_file(pw):
store = open('passcard.txt',"w")
for site,ID,passcard in sitelist.items():
store.write(site + '\n')
store.write(ID + '\n')
store.write(passcard + '\n')
store.close()
def main_menu():
print "1) Add a login info card"
print "2) Lookup a login info card"
print "3) Remove a login info card"
print "4) Print Login info list"
print "9) Save and Exit"
def add_site():
print "Add a login info card"
site = raw_input("Site: ")
ID = raw_input("User ID: ")
passcard = getpass.getpass("Password: ")
sitelist[site] = [ID,passcard]
def lookup_site():
print "Lookup a login info card"
site = raw_input("Site: ")
if sitelist.has_key(site):
print "The ID is: ",sitlist[site][0]
print "The password is: ",sitelist[site][1]
else:
print site," was not found."
def remove_site():
print "Remove a login info card"
site = raw_input("Site: ")
if sitelist.has_key(site):
del sitelist[site]
else:
print site," was not found."
def print_login_info():
print "Login Info"
for site in sitelist.keys():
print "Site: ",site," \tID: ",sitelist[site][0]," \tPassword: ",sitelist[site][1],"\n"
print "The Password Program"
print "By Nathan Pinno"
print
load_file(sitelist)
answer = getpass.getpass("What is the password? ")
while password != answer:
print "The password is incorrect."
answer = getpass.getpass("What is the password? ")
print "Welcome to the second half of the program."
while 1:
main_menu()
menu_choice = int(raw_input("Choose an option (1-4, or 9: "))
if menu_choice == 1:
add_site()
elif menu_choice == 2:
lookup_site()
elif menu_choice == 3:
remove_site()
elif menu_choice == 4:
print_login_info()
elif menu_choice == 9:
break
else:
print "That's not an option!"
save_file(sitelist)
print "Have a nice day!"
How do I fix the program, so that it will save the info without raising any errors?
