FASTAPI_Async_Python

This repository is exclusive to my studies In FAST API using Asyncio

RESOURCES

PARA QUE SERVE?

Lib para escrever codigo simultaneo usando sintaxe async/await. Asyncio fornece um conjunto de APIs de alto nível para:

  • executar corrotinas do Python simultaneamente e ter controle total sobre sua execução;
  • realizar IPC e E/S de rede;
  • controlar subprocessos;
  • distribuir tarefas por meio de filas;
  • sincronizar código simultâneo;

CÓDIGO ASSINCRONO

Código assíncrono apenas significa que a linguagem 💬 tem um jeito de dizer para o computador / programa 🤖 que em certo ponto, ele 🤖 terá que esperar por algo para finalizar em outro lugar. Vamos dizer que esse algo seja chamado "arquivo lento" 📝.

CONCORRÊNCIA E ASYNC/AWAIT

Para chamar as funções use await:

results = await some_library()

Desta forma, tem que declarar a função com async def:

@app.get('/')
async def read_results():
    results = await some_library()
    return results

Você somente pode usar await dentro de funções ASYNC DEF.
