Right now this would work, but I would prefer to do it with for loops and a list.

I've tried, but I cannot figure out how to get the name of the buttons that were created in the for loop.

```
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()

root.title("Chamber Calibration")

button0 = tk.Button(root, text="-65C", width = 25, relief='raised', command=lambda: toggle(0))
button0.grid(row = 0, column = 3)

button3 = tk.Button(root, text="0C", width = 25, relief='raised', command=lambda: toggle(3))
button3.grid(row = 3, column = 3)

button9.grid(row = 9, column = 3)

button10 = tk.Button(root, text="165C", width = 25, relief='raised', command=lambda: toggle(10))
button10.grid(row = 10, column = 3)

button11 = tk.Button(root, text="38C 15%RH", width = 25, relief='raised', command=lambda: toggle(11))
button11.grid(row = 11, column = 3)

button12 = tk.Button(root, text="38C 95%RH", width = 25, relief='raised', command=lambda: toggle(12))
button12.grid(row = 12, column = 3)

button13 = tk.Button(root, text="50C 95%RH", width = 25, relief='raised', command=lambda: toggle(13))
button13.grid(row = 13, column = 3)

button14 = tk.Button(root, text="85C 95%RH", width = 25, relief='raised', command=lambda: toggle(14))
button14.grid(row = 14, column = 3)

What I've tried:

```
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()

```

Any pointers would be appreciated.
