It depends what you mean by scaling.

If it's a software system designed to have fault redundance and high
performance across a cluster of machines, then it easily accomplishes
those things (I completed a VoIP SIP/H323 voice peering project last
year which uses Psycho, Pyro, PyJudy for Python, and integrates with
PowerDNS, MySQL, Quagga, FreeRadius & the proprietary Mera Systems MVTS
soft switch across a cluster beginning starting out with 6 servers.
It's primary function is to provide ENUM DNS lookups and route calls
between providers, but the project had performance, scalability and lookup
database update constraints - 10M number ranges, < 0.2s response time to
DNS queries regardless of load, and needed to withstand DOS attacks (two
boxes handle >20Mb/s of DNS traffic).  In addition to this, database
updates needed to occur with less than <1 second of outage across all
systems with guaranteed consistency).

On the other hand, if what you mean by scalability is that a language
provides a good environment for >1M lines of code across >50 developers,
then Python does not provide such things as true data hiding (i.e. no
private/protected data & methods), which might be an issue.  Static typing
might have larger benefits in such cases too.  Python 3000 has some
new features that help with that (e.g. typing hints for documentation
and tools).

There are some good horizontal-scaling web systems written in Python.
They easily scale for an ordinary "company web site".  Even a large
framework and CMS system like Plone (bloatware in comparison to most
web frameworks in Pyton) will scale well horizontally - see:


It's certainly good enough to use for a huge number of high-profile
(list includes Akamai, Novell, Oxfam and many others for their primary
web sites).

Other popular frameworks are Django and Turbogears, both of which scale
very well, but are somewhat younger.  If raw performance stats have
any meaning to you, then this article compares 6 different frameworks:
