tkinter AttributeError: 'GUI' object has no attribute

[pfdjhfuys]

Hi,

When I click the button I expect the entry to be populated. Instead I get the error "AttributeError: 'GUI' object has no attribute 'genPassText'".

What am I missing?

from tkinter import *

class GUI:
    def DoSomething(self):
        self.genPassText.delete(0, END)
        self.genPassText.insert(0,'Hello World')

    def __init__(self):
        # root window
        self.root = Tk()
        self.root.title("Demo")
        self.root.geometry("800x280")
        self.root.resizable(width=FALSE, height=FALSE)

        # pass length information
        genPassButton = Button(self.root, text = "Generate Password", command=self.DoSomething).grid(row=8, column=0, padx=5, pady=5)
        genPassText = Entry(self.root, width=80, bd=3, font=('Bold')).grid(row=8, column=1, padx=5, pady=5)
        


if __name__ == '__main__':
    mainwindow = GUI()
    mainloop()
    
  

Thanks,
