为了提高代码的可读性、可维护性,Python 在PEP 484中引入了类型提示( type hinting)。类型提示是 Python 中一个可选但非常有用的功能,可以使代码更易于阅读和调试 关于类型提示的介绍可以看: https://realpython.com/python-type-hints-multiple-types/#use-pythons-type-hints-for-one-piece-of-data-of-alterna...
These tools infer the type from return values and ensure that functions are returning the expected type. Be sure to take advantage of this useful function that can reveal the type hints of more complicated return types! Remove ads Conclusion Although type hinting is optional, it’s a useful ...

在较大的代码库中,使用类型提示(type hinting)和静态类型检查工具(如mypy)可以提高代码的可读性和健壮性。例如: def add_numbers(a: int, b: int) -> int: return a + b 这种方式虽然不是直接的类型检查,但可以帮助开发者更清晰地了解函数的预期输入和输出类型。 五、结论 通过使用type()、isinstance()和...
Typing Hintingas well as the typing library, where as we could specify a static type for variables and functions. Amongst the various features introduced in thePython Typing library, was the use of the Union function, which can be used to specify multiple possible types for a variable or ...

Python has a very dynamic type system which has its advantages where the types can be multiple types. It does, however, also make the code harder to read and follow, if the types are unknown. There is a module for Python called typing: h...
