pydantic 的一个优点是它内置了精确且有用的错误消息。 还有一些工具可以利用 JSON 等格式的现有架构验证。例如,Taplo是一个 TOML 工具包,可以根据 JSON 模式验证 TOML 文档。Taplo 也可用于Visual StudioCode,捆绑在Even Better TOML扩展中。 了解TOML:键值对 TOML 是围绕键值对构建的,这些键值对很好地映射到哈希...

Python 3 changes this behavior by making the separation between bytes (bytes) and text (str) more strict. Python 3 will throw an exception when trying to combine and compare the two types. The programmer has to explicitly convert from one type to the other to mix values from each. ...

The urge to combine this with a speech-to-text package likeSpeechRecognition or watson-word-watcher (which provides confidence values per word) is almost irresistible, but of course you don’t need complex projects to make use of parsedatetime: even allowing a user to type in a friendly and...
