How to close other window by python Tkinter?

I have following python code in Tkinter.

import tkinter as tk


def main_gui(login, s):
    login.quit()  # close login window

    win = tk.Tk()
    win.geometry('300x150') 

    name = tk.Label(win, text='Hello' + s.get())  # Hello David
    name.pack()
    win.mainloop()

# initial Tkinter frame
login = tk.Tk()
login.title('Login')
login.geometry('300x150')

# input user name
user_name_var = tk.StringVar()
user_name_var.set('David')
tk.Label(login, text='User name').place(x=10, y=50)
user_name = tk.Entry(login, textvariable=user_name_var)
user_name.place(x=100, y=50)

input_ok = tk.Button(win_login, command=lambda: main_gui(login, user_name), text='OK', width=15)
input_ok.place(x=100, y=90)

win_login.mainloop()

I want to close login window, but my code can not close it. How to solve it.

you can use the

root.withdraw()

function, this will close the window without completely destroying all of the root.after functions

You are almost there - only two details you have to adapt:

  1. The method to remove a widget in Tkinter is destroy, so login.quit() should be login.destroy().

  2. Once login is destroyed, the user_name Entry will also be destroyed, and you will not be able to get the name from it anymore. You should get the name earlier, e.g., directly in the lambda:

    ... lambda: main_gui(login, user_name.get()), ...
