Right, but if there's a different display for True, there's probably
also one for False.
if isinstance(x, bool):
print("<input type=checkbox" + x * " checked" + " name=foo>Foo")
print("Foo <input name=foo value=%d>" % x)
But you're right that checking for True specifically is best done as
an identity check.
if x is True:
elif x is False:
print("[ ] Foo")
