How does one use this? The tool mypy can be run on the Python modules and packages to ferret out problems, or confirm your awesomeness. In other words, I can write my_variable: int = 2 to hint that my_variable should always be an integer. While optional, Python does support static type hints. In other words, I can write my_variable = 2 without needing to specify that my_variable is indeed an integer, not a string. Python is a programming language that does not require static type declarations. At the same time, Typer is flexible enough to handle the complexity thrown at it.Īmong command line helper libraries for Python (such as argparse and Click), Typer is unique in its use of type hints. With Typer, you can write command line tools in Python, intuitively and easily.
