AttributeError: Label instance has no call method

I am making a test program using Tkinter, but I'm running into some trouble.

I'm trying to make a Rock, Paper, Scissors game on which the users always loses, but I get "Label has no call instance", here's the code:

#Rock papers & scissor

import Tkinter as tk

class App(tk.Tk):

    def setLabel(self):

        entry2 = self.entry.get()   

        if entry2 == "paper":
            self.l1(App, text="Scissors, you loose!")
        elif entry2 == "Paper":
            self.l1(text="Scissors, you loose!")
        elif entry2 == "PAPER":
            self.l1(text="Scissors, you loose!")
        elif entry2 == "rock":
            self.l1(text="Paper, you loose!")
        elif entry2 == "Rock":
            self.l1(text="Paper, you loose!")
        elif entry2 == "ROCK":
            self.l1(text="Paper, you loose!")
        elif entry2 == "Scissors":
            self.l1(text="Rock, you loose!")
        elif entry2 == "scissors":
            self.l1(text="Rock, you loose!")
        elif entry2 == "SCISSORS":
            self.l1(text="Rock, you loose!")
        elif entry2 == "scissor":
            self.l1(text="Rock, you loose!")
        elif entry2 == "Scissor":
            self.l1(text="Rock, you loose!")
        elif entry2 == "SCISSOR":
            self.l1(text="Rock, you loose!")
        else:
            self.l1(text="wat")

    def __init__(self):
        tk.Tk.__init__(self)
        self.entry = tk.Entry(self)
        self.btn = tk.Button(self, text="Go!", command=self.setLabel)
        self.l1 = tk.Label(self, text="Waiting...")
        self.entry.pack()
        self.btn.pack()
        self.l1.pack()


App().mainloop()
App().minsize(300, 100)
App().title("Test")

A few problems:

  1. self.l1(text='mytext') is incorrect. When you put the parentheses right after self.l1, you're trying to call that label like it's a function, but it's not a function. You have to call that label's config() method.
  2. At the bottom, you create an App object and loop it... then you create another, and another. Create one, save a reference, and then work with it.
  3. Your if branch was larger than it could be.
  4. The mainloop() call should be at the end.
  5. You misspelled "lose" (yes, that counts).

The following fixes these problems:

import Tkinter as tk

class App(tk.Tk):

    def setLabel(self):

        entry2 = self.entry.get().lower()
        if entry2.startswith('p'):
            self.l1.config(text="Scissors, you lose!")
        elif entry2.startswith('r'):
            self.l1.config(text="Paper, you lose!")
        elif entry2.startswith('s'):
            self.l1.config(text="Rock, you lose!")
        else:
            self.l1.config(text="wat")

    def __init__(self):
        tk.Tk.__init__(self)
        self.entry = tk.Entry(self)
        self.btn = tk.Button(self, text="Go!", command=self.setLabel)
        self.l1 = tk.Label(self, text="Waiting...")
        self.entry.pack()
        self.btn.pack()
        self.l1.pack()

app = App()
app.minsize(300, 100)
app.title("Test")
app.mainloop()
