TkInter Binding Buttons

[ifigazsi]

Yes, you can bind both a key and a button to the same function. You were really close with the lambda. All you had to do was throw away the event which you don't care about.

import tkinter as tk
 
root = tk.Tk()
root.geometry('250x100')
 
def check_in_database(data, chk):
    if data in chk:
        print(f'{data} was found in database.')
    else:
        print(f'{data} no match in database.')
 
chk_database = ['Eric', 'John', 'Graham', 'Terry']
 
field_entry = tk.Entry(root, width=20)
field_entry.bind("<Return>",
                 lambda event: check_in_database(field_entry.get(), chk_database))
field_entry.grid(row=0, column=0)
 
tk.Button(root, text='Check database',
          command=lambda: check_in_database(field_entry.get(), chk_database)) \
          .grid(row=0, column=1)
 
root.mainloop()

Another useful tool is functools.partial

Yes, you can bind both a key and a button to the same function.

Thank you! :D
