Maybe this is dumb -- but I'm perpetually bitten by it. Often times,
I want to factor a list of numbers. Sometimes, a zero will pop up in
the list, and I get an exception.
Ok, so there isn't a unique prime factorization of zero. But, there
isn't a unique prime factorization of a negative integer, either, but
we don't raise exceptions there.
My preference would be that factor works for all integers. It's not
like it's hard to factor 0 or anything. We just return the
factorization object [(0,1)].
Thoughts?
Of course this is easy to solve:
{{{
for a,b,c in data:
print a,b, factor(c)
}}}
just has to be
{{{
for a,b,c in data:
if c != 0:
print a, b, factor(c)
else:
print a,b, 0
}}}
but... the second is ugly and there's (IMHO) no reason for it.
