Run, don't walk, to the Python Tutorial. Work through each section, do
the examples, experiement to get an understanding of the examples, and
then continue.

syntax accesses an object's attributes.

Work through the tutorial from beginning to end to get a good grounding
in this and other fundamentals.

Welcome to the language, and enjoy your learning!
