Ok, so the error message is saying "I'm trying to call the
add_login_command, but as add_login_command is defined, it needs two
arguments. Isn't this weird?"
Let's look at the definition of add_login_command():
print "Add a login info card"
site = raw_input("Site: ")
id = raw_input("User ID: ")
passcard = raw_input("Password: ")
sitelist[site] = [id,passcard]
It's not clear to me why 'site' and 'filename' are in the argument list,
as neither are being used as arguments, and no matter what we pass into
add_login_command, it looks like the function just ignores whatever it
There are two possible ways of fixing this:
1. When calling add_login_command(), just pass random garbage for
those two parameters:
2. Correct add_login_command() so that it doesn't take in two
I do not like option one. *grin* I strongly recommend fixing the
parameter list for add_login_command() so that it doesn't ask for
parameters that it never uses.
Best of wishes!
