The easiest way to get the number of digits of a positive integer n is
len(str(n)) or even n.ndigits() !
So
sage: N=10^6
sage: sum([n.ndigits() for n in srange(1,N+1)])
596
solves your problem for all integers up to a million. This is
obviously not the fastest way though!

Hi,
I'm trying to create a function which outputs the number of digits you'd have to
write down to write every integer from 1 up to the input value.
Having defined x and z as variables I used this at one point...
z(x)=((int(log(x,10)))+1)*(1+x-((10^int(log(x,10)
It gets rejected as does using
It turns out that warnings are not visible to the end users anymore.
This is according to the python documentation:

Section 27.6.5 to be precise.
Actually more explicit in http://docs.python.org/using/cmdline.html :

Dear Sage Devs,
Thanks to an influx of grant money, I'm organizing a "huge" Sage Days
on the Sage Notebook June 13-17, 2011 in Seattle. That's in just over
two months from now. If you would like to come, send me an email.
Also, if you just want to come and fix lots of bugs in Sage, and

Thanks to Nicolas there is a lot of progress there. Initial test by my friend
Steve has shown that test failures is way down and the problems with
assertEqual seems to be mostly solved.
Next we have a number of warning messages that have changed and the number
of significant figures displayed by

Hi all,
interesting thread, let me toss in my 2 cents.
There are also Linux distributions which do not have gcc installed by
default, so users might fall into the "Cython is not usable" trap,
too. Python, from v2.7 on, has some new module called "sysconfig" (see
