I just recently realized that the comparison operator "is" actually
works for comparing numeric values. Now, I know that its intended use
is for testing object identity, but I have used it for a few other
things, such as type checking, and I was just wondering whether or not
it is considered bad pr

With all due respect, for some reason it seems to work on my machine.
Because I certainly agree with you about writing broken code.

I wrote a cool function decorator just for that purpose. It's posted on
the Python Decorator Library at:

I've been debugging a simulation I wrote a while ago, and it seems that
the problem is in the fft module itself. I'm trying a simple test by
just feeding the function a basic real gaussian. Obviously, I should
get back the same real gaussian, but what I get is not even close. Can
anyone help me? Th

Oops, sorry. I see what you mean. I was reading the docs for the
regular (complex) fft function, since that was what I was initially
having the bug with. I was just using the rfft to simplify things, but
I guess that was ironic. Anyway, I appreciate your help and don't mean
to burden you. Again, I
