No.1 Python does not scale well.
map<int,char*> x=new map<int,char*>();
vs
self.d={};
Python is 10x slower than C++ or Java. If you do _any_ kind of OO
programming, python is _very_ slow.
I have implemented a great little web content engine based on Python
and XML using PyXML, and it has _serious_ problems with large pages.
I've done alot of profiling work, and over 90% of the time is spend in
d={} and x=[] style calls.
No. 2. Python does not inteface with everything by a long shot
Case in point - no good native MS SQL Server Driver. No good PDF
reading libraries.
I love python alot, heck I wrote a whole web platform in it, but I'm
under no illusions that it's much heavier that C++/Java or PHP.
People using Zope have found the same things to be true when they ramp
up the load.
wxPython is seriously ruling, and you can create exe files with python
on windows too. It's a contender, but it's not the King yet in my
book.
No offence of anything, but I've seen what non-professional
programmers do in any language they get their hands on (Python, Java,
Access/VBA), and for the most part, they should stick to their day
job, and leave application development to people with good CS degrees
who understand what they are doing (not that all CS graduates know
what they are doing, they just have a better shot).
