Sebastián Ramírez: Pydantic 对于 FastAPI 来说至关重要,它简化了数据验证、序列化、解析和文档生成的过程,使得开发者能够更轻松地构建应用程序。我发现 Pydantic 在处理数据验证方面非常出色,它能够自动完成并提供线性错误,这大大提高了开发效率。在 FastAPI 中,我利用 Pydantic 的这些特性,使其成为一个超级简单和直观的工具。我个人也在各种数据处理场景中使用 Pydantic,包括 GitHub Actions,这证明了它的通用性和强大功能。我很高兴看到 Pydantic 现在被广泛应用于主要的 LLM 提供商和 SDK 中,成为构建各种应用的基础。
