keyboard binding in piano python

Question

how can I bind keyboard in piano using python GUI?

I tried using bind but I did not know how to use that.

btnCs = Button(ABC2,  height = 6, width = 6, bd = 4, text = "C#", font =('arial', 18 , 'bold'), bg = "black",  fg = "white", command = value_Cs)

I expect an example using the code given help me pls

No, but the snippet where you try to bind might help, what is your error? Maybe that's not needed either, I think this could be a duplicate of the question [here](https://stackoverflow.com/questions/13326940/python-tkinter-how-to-bind-key-to-a-button) — progmatico, May 25 '19 at 14:07
I want to use my keyboard instead of the button in GUI and I tried btnCs.bind("a", value_Cs) and it is not working. — Noel, May 25 '19 at 14:10
Try binding the key to the root window, not to the button widget. — progmatico, May 25 '19 at 14:13

Watch the console output running your function when you press the a key in your keyboard. You need to focus the tkinter window with the mouse. event=None is needed because the binded callback function gets passed an event object by the tkinter event loop (mainloop):

from tkinter import Tk

def play_a(event=None):
    print('Play the A key sound')

root = Tk()
root.bind('a', play_a)

root.mainloop()

You are welcome @Noel, see also [here](http://effbot.org/tkinterbook/tkinter-events-and-bindings.htm) about events and binding in tkinter. – progmatico May 25 '19 at 14:53
