Different implementations of Python (for instance, CPython versus CPython+Psyco) can vary in speed by more than a factor of 10 for particular blocks of Python code.

To be useful, every language has to be interpreted sometime by something. In the narrow technical sense that I presume you mean, 'interpretation' versus 'compilation' is again an implementation feature, not a language feature. As far as I know, neither Perl nor Python has an implementation that directly interprets in the way that Basic or tokenized Basic once was. I am being picky because various people have claimed that Python suffers in popularity because it is known as an 'interpreted language'. So maybe advocates should be more careful than we have been to not reinforce the misunderstanding. Terry J. Reedy -- http://mail.python.org/mailman/listinfo/python-list
