root.mainloop()This code creates a command button called "firstcommandbutton". This button calls the method "Second". Can I create code in Second, that gives me the name of the firstcommandbutton, and reads it into a variable.? If that is not possible can I get the text of the firstcommandbutton?
RE: Get name of command button - deanhystad - Dec-07-2020
Why? If you want to access the button that called a finction it is easier to just pass the button as an argument.
self.firstcommandbutton.configure(command=lambda x = self.firstcommandbutton: self.Second(x))
def second(button):
print(button['text']

This is how I changed the code based on your answer. It now gives me a
m = Main(root)

You should fix the syntax error. The error is not this line "m = Main(root)".
Here are a couple of methods that receive a widget as an argument and perform some action on the widget.
import tkinter as tk
class MyWindow:
def __init__(self, root):
frame = tk.Frame(root)
frame.pack(expand=True, fill=tk.BOTH)
label = tk.Label(frame, text="Press the Button")
label.pack(expand=True, fill=tk.BOTH, padx=5, pady=5)
button = tk.Button(frame, text="This is the Button")
button.config(command=lambda:self.button_pressed(button, label))
button.pack(expand=True, fill=tk.BOTH, padx=5, pady=5)
quitbn = tk.Button(frame, text="Quit", command=lambda:self.quit(root))
quitbn.pack(expand=True, fill=tk.BOTH, padx=5, pady=5)
def button_pressed(self, button, label):
label['text'] = 'The button was pressed'
button['state'] = tk.DISABLED
def quit(self, window):
print('Quitting')
window.destroy()
root = tk.Tk()
root.geometry('200x200')
MyWindow(root)
root.mainloop()
