Option 1 (tested):

def f(cnt=[0]):
    cnt[0] = cnt[0]+1
    print 'f called', cnt[0], 'times'

f()
f()
f()
f([1.1])
f()

# outputs

f called 1 times
f called 2 times
f called 3 times
f called 2.1 times
f called 4 times

#f(nonsubscriptable) gives typeerror

Option 2 (also tested)

def make_f():
    cnt=[0]
    def _():
        cnt[0] = cnt[0]+1
        print 'f called', cnt[0], 'times'
    return _

f = make_f()
f()
f()
f()

# again gives

f called 1 times
f called 2 times
f called 3 times

#f(anything) is typeerror
