Getting stdin using TextWrangler or BBEdit,
but not MacPython (was: [Pythonmac-SIG] One IDE can find sys._buf,
the other can't. What's going on?)

I don't know a damn thing about TextWrangler, but this works with any
Python that has a working stdin:
text = raw_input("Input 2 ints and a float: ")
i1, i2, f1 = [t(v) for (t, v) in zip((int, int, float),
except ValueError, e:
print 'Invalid Entry: %s' % (e,)
