MyrootDialog.geometry("300x100")

mytkcombo = ttk.Combobox(MyrootDialog, values=['SKO', 'Tech', 'Learn'])

MyrootDialog.geometry("300x100")

mytkcombo = ttk.Combobox(MyrootDialog)
# For Loop
for x in range(5):
   # Add itmes in combobox through Loop code
   mytkcombo['values']= tuple(list(mytkcombo['values']) + [str(x)])

#Set Tkinter window Size
MyrootDialog.geometry("300x100")

mytkcombo = ttk.Combobox(MyrootDialog)
# Define Array List
strList=['']
for mnt in range(1, 13):
   #Add Month Name through Loop
   strList.append(calendar.month_name[mnt])
#Add Items in Tkinter Combobox through Array
mytkcombo['values'] = strList
