\subsection{Why use wxPython?}\label{wxpwhy}
So why would you want to use wxPython over just C++ and wxWindows?
So why would you want to use wxPython over just C++ and wxWidgets?
Personally I prefer using Python for everything. I only use C++ when I
absolutely have to eke more performance out of an algorithm, and even
then I usually code it as an extension module and leave the majority
of the program in Python.
Another good thing to use wxPython for is quick prototyping of your
wxWindows apps. With C++ you have to continuously go though the
wxWidgets apps. With C++ you have to continuously go though the
edit-compile-link-run cycle, which can be quite time consuming. With
Python it is only an edit-run cycle. You can easily build an
application in a few hours with Python that would normally take a few
days or longer with C++. Converting a wxPython app to a C++/wxWindows app
days or longer with C++. Converting a wxPython app to a C++/wxWidgets app
should be a straight forward task.
