Ho risolto il problema della riga 27, ho messo un tab......e non esce più errore.
Adesso esce errore alla riga 9:
line 9, in <module>
style = Style()
NameError: name 'Style' is not defined
# import everything from tkinter module
from tkinter import *
# create a tkinter window
root = Tk()
# Open window having dimension 100x100
root.geometry('1100x600')
root.title("Campionati di Calcio Serie A e B")
style = Style()
style.configure('TButton', font = ('calibri', 20, 'bold'), borderwidth = '4')
# Changes will be reflected
# by the movement of mouse.
style.map('TButton', foreground = [('active', '! disabled', 'green')], background = [('active', 'black')])
# Create a Button 1
btn1 = Button(root, text = 'Risultati', bd = '5', command = None)
btn1.grid(row = 0, column = 3, padx =10)
# ''' Button 2'''
btn2 = Button(root, text = 'Classifica', bd = '5', command = None)
btn2.grid(row = 1, column = 3, pady = 10, padx = 20)
# Note Set the position of button on the top of window.
# btn.pack(side = 'left')
if __name__ == '__main__':
root.mainloop()
