Question

现在这可行，但我更愿意使用for循环和列表。

我已经尝试了，但我无法弄清楚如何获取在for循环中创建的按钮的名称。

import tkinter as tk

def toggle(button):
  #----------------------------
  # Manages the button toggling
  #----------------------------
  if button == 0:
    if button0.config('relief')[-1] == 'sunken':
      button0.config(relief='raised')
    else:
      button0.config(relief='sunken')
  if button == 1:
    if button1.config('relief')[-1] == 'sunken':
      button1.config(relief='raised')
    else:
      button1.config(relief='sunken')
  if button == 2:
    if button2.config('relief')[-1] == 'sunken':
      button2.config(relief='raised')
    else:
      button2.config(relief='sunken')
  if button == 3:
    if button3.config('relief')[-1] == 'sunken':
      button3.config(relief='raised')
    else:
      button3.config(relief='sunken')
  if button == 4:
    if button4.config('relief')[-1] == 'sunken':
      button4.config(relief='raised')
    else:
      button4.config(relief='sunken')
  if button == 5:
    if button5.config('relief')[-1] == 'sunken':
      button5.config(relief='raised')
    else:
      button5.config(relief='sunken')
  if button == 6:
    if button6.config('relief')[-1] == 'sunken':
      button6.config(relief='raised')
    else:
      button6.config(relief='sunken')
  if button == 7:
    if button7.config('relief')[-1] == 'sunken':
      button7.config(relief='raised')
    else:
      button7.config(relief='sunken')
  if button == 8:
    if button8.config('relief')[-1] == 'sunken':
      button8.config(relief='raised')
    else:
      button8.config(relief='sunken')
  if button == 9:
    if button9.config('relief')[-1] == 'sunken':
      button9.config(relief='raised')
    else:
      button9.config(relief='sunken')
  if button == 10:
    if button10.config('relief')[-1] == 'sunken':
      button10.config(relief='raised')
    else:
      button10.config(relief='sunken')
  if button == 11:
    if button11.config('relief')[-1] == 'sunken':
      button11.config(relief='raised')
    else:
      button11.config(relief='sunken')
  if button == 12:
    if button12.config('relief')[-1] == 'sunken':
      button12.config(relief='raised')
    else:
      button12.config(relief='sunken')
  if button == 13:
    if button13.config('relief')[-1] == 'sunken':
      button13.config(relief='raised')
    else:
      button13.config(relief='sunken')
  if button == 14:
    if button14.config('relief')[-1] == 'sunken':
      button14.config(relief='raised')
    else:
      button14.config(relief='sunken')




root = tk.Tk()

我尝试过的事情：

import tkinter as tk

def toggle(button):
  if button == 0:
    if button0.config('relief')[-1] == 'sunken':
      button0.config(relief='raised')
    else:
      button0.config(relief='sunken')

root = tk.Tk()

root.title("Chamber Calibration")

#------------------------------------------
# Sets up the different temperature buttons
#------------------------------------------

STEPS = ['-65C', '-40C', '-20C', '0C', '23C', '30C', '45C', '65C', '90C', '130C', '165C',
         '38C 15%RH', '38C 95%RH', '50C 95%RH', '85C 95%RH']

count = 0
for step in STEPS:
    newname = ('button' + str(count))
    print(newname)
    newname = tk.Button(root, text=step, width = 25, relief='raised',
                        command=lambda button=count: toggle(button))
    newname.grid(row = count, column = 3)
    count += 1

#-----------
# Starts GUI
#-----------
root.mainloop()

任何指针都会受到赞赏。

Answer 1

不要尝试创建变量名称，只需将按钮存储在列表中：

buttons = []
for step in STEPS:
    buttons.append(tk.Button(...))
    ...

...
buttons[i].configure(...)

Answer 2

正如旁注，你已经死了布莱恩，谢谢你。这是工作代码：

import tkinter as tk

def toggle(num):
    if buttons[num].config('relief')[-1] == 'sunken':
      buttons[num].config(relief='raised')
    else:
      buttons[num].config(relief='sunken')

root = tk.Tk()

root.title("Chamber Calibration")

#------------------------------------------
# Sets up the different temperature buttons
#------------------------------------------

STEPS = ['-65C', '-40C', '-20C', '0C', '23C', '30C', '45C', '65C', '90C', '130C', '165C',
         '38C 15%RH', '38C 95%RH', '50C 95%RH', '85C 95%RH']

buttons = []
count = 0
for step in STEPS:
    buttons.append(tk.Button(root, text=step, width = 25, relief='raised',
                        command=lambda num=count: toggle(num)))
    buttons[count].grid(row = count, column = 3)
    count += 1

# Starts GUI

root.mainloop()
