Not exactly. The line '#!/usr/bin/env python' is not required at
all; it is only used when a script is being run as the main program
from a shell, or when double-clicked. For the vast majority of
scripts, such as modules and those containing class definitions, this
line is useless.
However, the line that reads: '# -*- coding: utf-8 -*-' is
critically important for *all* platforms. Python will throw an error
if your script contains a non-ASCII character and does not declare
the encoding:
SyntaxError: Non-ASCII character '\xc3' in file test.py on line 1,
but no encoding declared; see http://www.python.org/peps/
pep-0263.html for details

FWIW, it runs exactly as expected on wxPython 2.8.6.0 on Ubunty Feisty.

Another bad choice. On a Mac, buttons can grow horizontally, but
cannot expand vertically.

The dSizer demo in DaboDemo shows the effect of the various sizer
settings pretty well, allowing you to change them interactively to
see what difference each makes.
