Frédéric, you should upgrade to Python 1.5.2! This was fixed a long time
ago (1.5.2 was released more than a year ago).

> Subject: [Python-bugs-list] bug in complex_nonzero (PR#347)
> Full_Name: Frédéric van der Plancke
> Version: 1.5.1
> OS: Windows NT 4
> Submission from: i0913.bfp-s.euronet.be (22.214.171.124)
> There is a bug in the test for non-nullity of a complex number.
> e.g. not (1j), not (4+0j) both return 1.
> (they should return 0, like (not n) for any non-null number n.)
> correction in <complexobject.c>:
> '||' instead of '&&' in complex_nonzero(v):
> static int
> PyComplexObject *v;
> return v->cval.real != 0.0 || v->cval.imag != 0.0;
> (Warning: I did not test my correction ;-)
