I am trying to create a password manager in Python and I am getting an Value Error. Below is my code that I’ve written for the password manager. It uses inputs for password.
def view():
with open("passwords.txt", "r") as f:
for line in f.readline():
data = (line.rstrip())
user, passw = data.split("|")
print("User: ", user, "password", passw)
def add():
name = input("Account Name: ")
pwd = input("Password:" )
with open("passwords.txt", "a") as f:
f.write(name + "|" + pwd + "\n")
while True:
mode = input ("Would you like to add a new password or view existing ones (view, add). Press q to quit").lower()
if mode == "q":
quit()
if mode == "view":
view()
elif mode == "add":
add()
else:
print("You have entered an invalid mode")
continue
Here is the error I’m getting when running and entering inputs:
File "C:\Users\user\Documents\Python\exercises\passwordmanag.py", line 22, in <module>
view()
File "C:\Users\user\Documents\Python\exercises\passwordmanag.py", line 8, in view
user, passw = data.split("|")
ValueError: not enough values to unpack (expected 2, got 1)
Can someone please help me out and guide me on how to fix this error?
Thank you.
>Solution :
def view():
with open("passwords.txt", "r") as f:
for line in f:
data = (line.rstrip())
user, passw = data.split("|")
print("User: ", user, "password", passw)
def add():
name = input("Account Name: ")
pwd = input("Password:" )
with open("passwords.txt", "a") as f:
f.write(name + "|" + pwd + "\n")
while True:
mode = input ("Would you like to add a new password or view existing ones (view, add). Press q to quit").lower()
if mode == "q":
quit()
if mode == "view":
view()
elif mode == "add":
add()
else:
print("You have entered an invalid mode")
continue
Context: You were trying to read each character of the line rather than reading each line therefore it was giving you an error when trying to split.
