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:

while True:
     text = raw_input("Input 2 ints and a float: ")
     try:
         i1, i2, f1 = [t(v) for (t, v) in zip((int, int, float), 
text.split())]
     except ValueError, e:
         print 'Invalid Entry: %s' % (e,)
         continue
     break
