Hi,
Which is the preferred way of string formatting?
(1) "the %s is %s" % ('sky', 'blue')
(2) "the {0} is {1}".format('sky', 'blue')
(3) "the {} is {}".format('sky', 'blue')
As I know (1) is old style. (2) and (3) are new but (3) is only
supported from Python 2.7+.
Which one should be used?

PIL 1.1.6 also uses its internal C library to speed things up.
For Windows you should use the precompiled packages.

Thanks for the advice, py2exe seems to be a great tool.
Unfortunately the application stops executing at the same place. It

Writing x*x instead of x**2 is obsolete, but it will never go away.
Writing apply(func, args) instead of func(*args) is deprecated. It has

I'm trying to learn PyGTK and Glade. I made test window in Glade and
saved it as "test.glade" (attached). Then I wrote script
