python - tkinter call two functions

Is it possible to make it so that a Tkinter button calls two function?

some thing like this maybe?:

from Tkinter import *

admin = Tk()
def o():
    print '1'

def t():
    print '2'
button = Button(admin, text='Press', command=o, command=t)
button.pack()

Make a new function that calls both:

def o_and_t():
    o()
    t()
button = Button(admin, text='Press', command=o_and_t)

Alternatively, you can use this fun little function:

def sequence(*functions):
    def func(*args, **kwargs):
        return_value = None
        for function in functions:
            return_value = function(*args, **kwargs)
        return return_value
    return func

Then you can use it like this:

button = Button(admin, text='Press', command=sequence(o, t))
