基础数据类型像是int,float,str,bytes 可以在type hints中直接使用,其他已经封装好的类,也可以直接在type hint中使用。当然抽象类(Abstract Base Classes)在type hint中也很有用。 Optional and Union types 上面2个类型还是比较常见的,我们先来看个例子: from typing import Optional def show_count(count: int,...
尽管Python 3.5+中才将类型库添加到标准库中,但它可以作为Python 2.7+的PyPi包使用。此外,由于Python注释是任何Python代码下的有效语言特性,因此可以在Python 2.7或更高版本上代码中加入类型提示。有一些要求:类型提示注释(type hint comment)必须位于函数/变量定义所在的相同或下一行。 它也以type:constant 开始。 此...

Python has three distinct numeric types: Integers: Represent whole numbers, both positive and negative, without fractional parts. Floating-point numbers: Represent numbers with decimal points. Complex numbers: Used in engineering and science, containing a real and imaginary part (e.g., A + Bi)....
Enforce.pyis a Python 3.5+ library for integration testing and data validation through configurable and optional runtime type hint enforcement. It uses the standard type hinting syntax (defined in PEP 484). NOTICE:Python versions 3.5.2 and earlier (3.5.0-3.5.2) are now deprecated. Only Python...
I'm not sure, I don't think it's possible. I don't think you can modify the output type based on an argument's value. I think the best we can do is overload the function with all the type specializations we would care about. https://docs.python.org/3/library/typing.html#typing...
