Use the winfo_class() method (Example below):
from Tkinter import *
r = Tk()
b = Button(r, text='test')
b.pack()
c = Checkbutton(r)
c.pack()
e = Entry(r)
e.pack()
widgets = [b,c,e]
def widgetMethod(widget):
if widget.winfo_class() == 'Button':
print 'A Button widget!'
elif widget.winfo_class() == 'Checkbutton':
print 'A Checkbutton widget!'
elif widget.winfo_class() == 'Entry':
print 'An Entry widget!'
for widget in widgets:
widgetMethod(widget)
r.mainloop()
