Watch Out for Snakes! A Byte-Sized Introduction to Python
summary
Practical checklist for Java-to-Python migration: target Python 3.10, run python3 --version in builds, and avoid Python 2.x; follow PEP8 and prefer f-strings over %-formatting or str.format; treat bytes vs str explicitly and encode/decode at I/O boundaries; skip the surprising else on for/while idiom; expect immutable tuples, mutable lists/dicts/sets, and useful extras like collections.Counter and deque; try pyfunctional for immutable map/filter/reduce pipelines; live REPL demos run but show minor hiccups (lights flicker).
