Generators Will Free Your Mind
summary
Claims that generators remove API-mode assumptions and avoid needless work with lazy streams. Demos show a 50-line meeting scheduler, a trading-query case where a list-returning API blows memory on millions of trades and a generator fixes it, and a Fibonacci example composed with itertools.islice and generator expressions to select values. Techniques include composing streams, co-routines send() for ordered callbacks, and a greedy coin algorithm built from chained generators. Notes caveat that generators can be slower but let slow parts be swapped for C extensions.
