Python just uses machine doubles by default. You might be able to edit
the source so it uses, say, 80-bit extended floats if you're on a machine
that supports them (like the x86). Those do support larger exponents.
You could also use something like gmpy, which supports arbitrary size
and arbitrary precision numbers. Of course it's slow by comparison.

You could rearrange your formulas to not need such big numbers:
x = 1000.
log10_z = x / math.log(10)
c,m = divmod(log10_z, 1.)
print 'z = %.5fE%d' % (10.**c, m)
