Question

我是python和tkinter的新手，在我的程序中我创建了多个标签并且运行良好，但我的问题是我需要稍后重新配置我的按钮，例如，如果按钮X单击然后更改第3标签颜色我和我的所有标签都有相同的名称 ll229 ，我试图使用像ll229 [3] .config这样的索引（做某事），但它没有用。

def update_ref_str():
  for i in range(ref_counter):

  ref_codes_str[i].set(ref_codes[i])
  ref_obj_per_codes_str[i].set(ref_obj_per_code[i])
  ref_time_needed_str[i].set(ref_time_needed_per_task[i])

  ll229 = Label(f2, textvariable = ref_codes_str[i] , bg='springgreen2',fg="gray23")
  ll229.config(font=("Helvetica", 13))
  ll229.place(bordermode=OUTSIDE, height=18, width=100, x=573, y=100 + 20*i )

  ll33 = Label(f2, textvariable = ref_obj_per_codes_str[i] , bg='springgreen2' , fg="gray23")
  ll33.config(font=("Helvetica", 13))
  ll33.place(bordermode=OUTSIDE, height=18, width=59, x=677, y=100 + 20*i)

  ll44 = Label(f2, textvariable = ref_time_needed_str[i] , bg='springgreen2',fg="gray23")
  ll44.config(font=("Helvetica", 13))
  ll44.place(bordermode=OUTSIDE, height=18, width=58, x=740 , y=(100 + 20*i))

这个问题显示了一个类似于你所使用的东西的例子，但是使用了入口小部件

example with entry widgets

或多或少 - 如果您设置了标签的名称，例如> [0664:26A0][2018-05-09T03:16:16]i000: > MainViewModel.OnPackageActionProgress: Percent completed: 50, Overall > progress: 3 [1830:047C][2018-05-09T03:16:16]e000: Error 0x800703f3: > Process returned error: 0x3f3 [1830:047C][2018-05-09T03:16:16]e000: > Error 0x800703f3: Failed to execute EXE package. > [0664:26A0][2018-05-09T03:16:16]e000: Error 0x800703f3: Failed to > configure per-machine EXE package. > [0664:26A0][2018-05-09T03:16:16]i000: MainViewModel.OnPackageAction: > Install Completed for package SQL Server Analysis Services (id: > Microsoft.DataTools.AnalysisServices) > [0664:26A0][2018-05-09T03:16:16]i319: Applied execute package: > Microsoft.DataTools.AnalysisServices, result: 0x800703f3, restart: > None [0664:26A0][2018-05-09T03:16:16]e000: Error 0x800703f3: Failed to > execute EXE package.

获取文字：

f2

同样，配置：

f2.children['l1'].get()

如何索引你的tkinter标签？
