[Tkinter] check if entry is null

[rwahdan]

Hi,

I am trying to check if an entry is null but not succeeded to do so.

1 2 3 4 5 6 7 8 9

cap_entry = sec_entry.get()     if cap_entry in str(image_rand):         complete_purchase()     elif not cap_entry:         cvv_screen.destroy()         cart()     else:         cvv_screen.destroy()         cart()

if I leave the entry field empty it goes to first if statement which goes to complete_purchase().

Here is an example code that prints either Entry has a value or Entry is empty

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

import tkinter as tk from tkinter import ttk     class TkApp(tk.Tk):     def __init__(self, *args, **kwargs):         super().__init__(*args, **kwargs)         self.entry = ttk.Entry(self)         self.entry.pack(padx=5, pady=5)         self.button = ttk.Button(self, text='Print', command=self.on_button)         self.button.pack(pady=5)       def on_button(self):         entry_value = self.entry.get()         print(f'Entry contains: {entry_value}')         if entry_value:             print('Entry has a value')         else:             print('Entry is empty')     if __name__ == '__main__':     app = TkApp()     app.mainloop()
