按下按钮后如何编辑标签

Question

button = Button(frame, text = "...", font = ('Courier', 14), command = lambda: principal_function(entry.get()))
button.place(relx = 0.7, relwidth = 0.3, relheight = 1)

label:

generalLabel = Label(lower_frame, text = '..', font = ("Courier", 22))
generalLabel.place(relwidth = 1, relheight = 1)`enter code here`
generalLabel.pack()

如果按下按钮，我想用新文本更新标签

Answer 1

这应该起作用，更新标签的配置

generalLabel.config(text="changed")
