With your original code, the elements of array2 are strings, and here

Whoops, that should have been x[b], not x[a]. Why is it that a
post-submission proofread turns up errors so much more often than a
pre-submission

Hi,
I have the following FFT python code and it doesn't seem to compile
correctly. To run it, please create a file called output.csv with
1,2,3,4,5,6,7,8. simply run the main function. I get an error such as
the following:
x[a], x[b] = x[(a)] + W[(n % N)] * x[(b)], x[(a)] - W[(n % N)] * x

You didn't seriously implement an FFT in plain Python code, did you? FFTs
are amongst the first thing that come to my mind when I try to imagine what
I'd use NumPy for. (and I *never* used it!)

Sorry, no, you didn't. Should have read your post a little closer.

I got another problem after changing / to // . Yes, I am using 3.1.
W.append(exp(sign * 2j * pi * i // N))
TypeError: can't take floor of complex number.
Don't change it everywhere, just where it deals with integers. In the
above, / is perfectly right.
