NameError: name 'delete' is not defined-CodePudding

Hello I have recently been learning python and I was practicing ... I just can't understand the reason for the error as it seems to me that I define inside the buttons. If someone kindly can help me I would be very grateful

I don't know how to go on anymore and I don't understand where the mistake is, I would like to be able to understand it but I can't do it, can you explain it to me?

CodePudding user response：

change name your function to another name delete

CodePudding user response：

This line

b1 = tk.Button(windows, text="Importa", command=delete ,width=8,`enter code here`height=1).place(x=170,y=310)

Attaches the button to the delete function, however, at the time you're executing it you haven't defined the delete function (you do that slightly later).

Try moving that line below your def delete():
