Speed, basically. CPython is on the slow side. This is not
inherent in the language; it's an implementation problem.
The Shed Skin compiler is approaching C speeds,
but you have to accept some modest restrictions on run-time dynamism.
Also, CPython does not use multiple processors well. In fact,
multiple cores make CPython performance worse. (There's a long
analysis of this that's been discussed here recently.)
Personally, I consider Python to be a good language held back by
too-close ties to a naive interpreter implementation and the lack
of a formal standard for the language.
