Well, this would probably be as useful in most situations,
since the need to differentiate types that carefully is probably
rare:

try:
    num = float(str)
    print 'Do generic number stuff here'
except ValueError:
    print "Value not a number"

Obviously you know you could do that, since you were
able to come up with the more complex version above.
My point is merely that it is unlikely anything so
complex would often be necessary, so the "simpler way"
is perhaps just this little version.
