如何使用 for 循环按名称修改变量？

Question

b1 = Button(win,padx = 70,pady = 70,bg = "gray", command = lambda: click(b1))

b2 = Button(win,padx = 70,pady = 70, command = lambda: click(b2))

b3 = Button(win,padx = 70,pady = 70, command = lambda: click(b3))

b4 = Button(win,padx = 70,pady = 70, command = lambda: click(b4))

b5 = Button(win,padx = 70,pady = 70, command = lambda: click(b5))

b6 = Button(win,padx = 70,pady = 70, command = lambda: click(b6))

b7 = Button(win,padx = 70,pady = 70, command = lambda: click(b7))

b8 = Button(win,padx = 70,pady = 70, command = lambda: click(b8))

b9 = Button(win,padx = 70,pady = 70, command = lambda: click(b9))

for n in range(10):

    bn.configure(text=="something") #To modify all buttons with loop

如何使用for循环动态修改按钮的名称？

Answer 1

如果b1-b2在您的全局范围内定义并且您想通过它们的名称动态访问它们，您可以使用gloabls()：b1 = Button(win,padx = 70,pady = 70,bg = "gray", command = lambda: click(b1))b2 = Button(win,padx = 70,pady = 70, command = lambda: click(b2))b3 = Button(win,padx = 70,pady = 70, command = lambda: click(b3))b4 = Button(win,padx = 70,pady = 70, command = lambda: click(b4))b5 = Button(win,padx = 70,pady = 70, command = lambda: click(b5))b6 = Button(win,padx = 70,pady = 70, command = lambda: click(b6))b7 = Button(win,padx = 70,pady = 70, command = lambda: click(b7))b8 = Button(win,padx = 70,pady = 70, command = lambda: click(b8))b9 = Button(win,padx = 70,pady = 70, command = lambda: click(b9))for n in range(1,10):    bn = globals()["b{}".format(i)]    bn.configure(text=="something") #To modify all buttons with loop

Answer 2

创建一个按钮字典，即dict_button = {}for n in range(10):     dict_button['b'+ str(n)].configure(text=="something")并将字典中的按钮保持为dict_button['b1'] = Button(win,padx = 70,pady = 70,bg = "gray", command = lambda: click(b1))
