Concurrency and parallelism in Python

Concurrency is about dealing with lots of things at once. Parallelism is about doing lots of things at once.-- Rob Pike, co-inventor da linguagem Go - Concurrency is not Parallelism (it's better)

Ao preparar vários pratos ao mesmo tempo o cozinheiro está trabalhando de forma concorrente, porque normalmente ele só cuida de um prato por vez, mas vários estão sendo preparados ao mesmo tempo.Por outro lado, um fogão de 6 bocas permite aquecer 6 panelas em paralelo.Ou seja, o cozinheiro trabalha em modo concorrente e o fogão em modo paralelo.--Garoa Hacker Clube
