Print extremely large long in scientific notation in python

Question

Is there a way to get python to print extremely large longs in scientific notation? I am talking about numbers on the order of 10^1000 or larger, at this size the standard print

Answer 1

gmpy to the rescue...:

>>> import gmpy
>>> x = gmpy.mpf(10**1000)
>>> x.digits(10, 0, -1, 1)
'1.e1000'

I'm biased, of course, as the original author and still a committer of gmpy, but I do think it eases tasks such as this one that can be quite a chore without it (I don't know a simple way to do it without some add-on, and gmpy's definitely the add-on I'd choose here;-).
