Se voc\u00ea precisa criar uma API REST r\u00e1pida e eficiente em Python, o FastAPI<\/strong> \u00e9 uma das melhores op\u00e7\u00f5es. Ele \u00e9 otimizado para desempenho e suporta valida\u00e7\u00e3o autom\u00e1tica de dados.<\/p>\n\n\n\n

Neste tutorial, voc\u00ea aprender\u00e1 como criar uma API REST do zero<\/strong> com FastAPI.<\/p>\n\n\n\n
