CodePudding user response：

You need to define the function before you try to reference it.

def start_game_pressed (self):
    print("sus")

start_game = Button (text_box,command=start_game_pressed, fg='black',text = """                                               
丂七闩尺七
""")

CodePudding user response：

You need to write your function before referencing it in the button. Something like this:

# Notice that here, the function is 
# defined before the button is.

def start_game_pressed(self):
    print(“sus”)
start_game = Button(text_box,command=start_game_pressed, 
    fg='black',text = "丂七闩尺七")
