I just created a tkinter where you create a username and password, than you log in and can create or view the items you've added to your list. The username and password part of the program is fine, but when you get to the label adding part, it won't add the list labels.

from tkinter import *

import os



 creds = 'tempfile.temp' # This just sets the variable creds to 'tempfile.temp'



def Signup(): # This is the signup definition, 

    global pwordE # These globals just make the variables global to the entire script, meaning any definition can use them

    global nameE

    global roots



    roots = Tk() # This creates the window, just a blank one.

    roots.title('Signup') # This renames the title of said window to 'signup'

    intruction = Label(roots, text='Please Enter new Credidentialsn') # This puts a label, so just a piece of text saying 'please enter blah'

    intruction.grid(row=0, column=0, sticky=E) # This just puts it in the window, on row 0, col 0. If you want to learn more look up a tkinter tutorial :)



    nameL = Label(roots, text='New Username: ') # This just does the same as above, instead with the text new username.

    pwordL = Label(roots, text='New Password: ') # ^^

    nameL.grid(row=1, column=0, sticky=W) # Same thing as the instruction var just on different rows. :) Tkinter is like that.

    pwordL.grid(row=2, column=0, sticky=W) # ^^



    nameE = Entry(roots) # This now puts a text box waiting for input.

    pwordE = Entry(roots, show='*') # Same as above, yet 'show="*"' What this does is replace the text with *, like a password box :D

    nameE.grid(row=1, column=1) # You know what this does now :D

    pwordE.grid(row=2, column=1) # ^^



    signupButton = Button(roots, text='Signup', command=FSSignup) # This creates the button with the text 'signup', when you click it, the command 'fssignup' will run. which is the def

    signupButton.grid(columnspan=2, sticky=W)

    roots.mainloop() # This just makes the window keep open, we will destroy it soon



 def FSSignup():

    with open(creds, 'w') as f: # Creates a document using the variable we made at the top.

        f.write(nameE.get()) # nameE is the variable we were storing the input to. Tkinter makes us use .get() to get the actual string.

        f.write('n') # Splits the line so both variables are on different lines.

        f.write(pwordE.get()) # Same as nameE just with pword var

        f.close() # Closes the file



    roots.destroy() # This will destroy the signup window. :)

    Login() # This will move us onto the login definition :D



def Login():

    global nameEL

    global pwordEL # More globals :D

    global rootA



    rootA = Tk() # This now makes a new window.

    rootA.title('Login') # This makes the window title 'login'



    intruction = Label(rootA, text='Please Loginn') # More labels to tell us what they do

    intruction.grid(sticky=E) # Blahdy Blah



    nameL = Label(rootA, text='Username: ') # More labels

    pwordL = Label(rootA, text='Password: ') # ^

    nameL.grid(row=1, sticky=W)

    pwordL.grid(row=2, sticky=W)



    nameEL = Entry(rootA) # The entry input

    pwordEL = Entry(rootA, show='*')

    nameEL.grid(row=1, column=1)

    pwordEL.grid(row=2, column=1)



    loginB = Button(rootA, text='Login', command=CheckLogin) # This makes the login button, which will go to the CheckLogin def.

    loginB.grid(columnspan=2, sticky=W)



    rmuser = Button(rootA, text='Delete User', fg='red', command=DelUser) # This makes the deluser button. blah go to the deluser def.

    rmuser.grid(columnspan=2, sticky=W)

    rootA.mainloop()



def CheckLogin():

    with open(creds) as f:

        data = f.readlines() # This takes the entire document we put the info into and puts it into the data variable

        uname = data[0].rstrip() # Data[0], 0 is the first line, 1 is the second and so on.

        pword = data[1].rstrip() # Using .rstrip() will remove the n (new line) word from before when we input it









    if nameEL.get() == uname and pwordEL.get() == pword: # Checks to see if you entered the correct data.

        r = Tk() # Opens new window

        r.title(':D')

        r.geometry('250x100') # Makes the window a certain size

        stuff = 

        def addListItem():

            josh = entry100.get()

            stuff.append(josh)

            labels = Label(re, label=stuff)

            labels.pack()



        rlbl = Label(r, text='n[+] Logged In') # "logged in" label

        rlbl.pack() # Pack is like .grid(), just different

        rlbl = Label(r, text='nWelcome back, ' + nameEL.get())

        rlbl.pack()

        rlbl = Label(r, text='nThis is your list: ')

        if len(stuff) == 0:

            re = Tk()

            re.title('suh g, no stuff')

            re.geometry('300x300')

            rlbl = Label(re, text='There is no items in this lists directory')

            rlbl.pack()

            entry100 = Entry(re)

            entry100.pack()

            butt68 = Button(re, text="Create List Item", command=addListItem)

            butt68.pack()

        if len(stuff) != 0:

            re = Tk()

            re.title('items of your list')

            re.geometry('300x300')

            rlbl = Label(re, text=stuff)

        rlbl.pack()

        rlbl = Label

        r.mainloop()

    else:

        r = Tk()

        r.title(':D')

        r.geometry('150x50')

        rlbl = Label(r, text='n[!] Invalid Login')

        rlbl.pack()

        r.mainloop()



def DelUser():

    os.remove(creds) # Removes the file

    rootA.destroy() # Destroys the login window

    Signup() # And goes back to the start!



if os.path.isfile(creds):

    Login()

    Signup()

The error that shows up is

Exception in Tkinter callback

Traceback (most recent call last):

_tkinter.TclError: unknown option "-label"

I think the error has to do with the labels = Label(re, text=stuff), because I am putting a whole list where there should only be one piece of text. If anyone knows how to fix this, that would be greatly appreciated if you could share that with me.

Just like the error is telling you, label is not something Label supports. You need to use text.
