无需额外安装,只需确保项目中已使用类型注解,PyCharm就能自动进行类型检查。在设置中开启或关闭类型检查也很简单 ,进入“Settings” > “Editor” > “Inspections” ,确保“Type Checking”下的相关选项已被勾选。 5.2.2 PyCharm中查看与利用类型提示 PyCharm不仅仅在编写代码时即时显示类型错误 ,还提供了丰富的代...
defmultiply(numbers:Sequence[Numeric]) -> Numeric: total: Numeric =1fornumberinnumbers: total *= numberreturntotal 当然mypy 也提供了一种让我们忽略掉可能被检查到并提示错误的机制,即我们可以通过注释来进行标注: defmultiply(numbers:Sequence[Numeric]) -> Numeric: total =1fornumberinnumbers: total *=...

这就是为什么它不被导入,我们只能在typing.TYPE_CHECKING保护的if块内调用它,这个块只有在静态类型检查器的眼中才是True,但在运行时是False。示例13-19 中的两个测试都通过了。Mypy 在该代码中没有看到任何错误,并显示了pick返回的item上reveal_type的结果:...
