交互式 prompt​

typer.prompt​

使用 typer.prompt 以交互式方法输入参数

if you absolutely need to ask for interactive information without using a CLI option, you can use typer.prompt():

import typer


def main():
    person_name = typer.prompt("What's your name?")
    print(f"Hello {person_name}")


if __name__ == "__main__":
    typer.run(main)

typer.confirm​

import typer


def main():
    delete = typer.confirm("Are you sure you want to delete it?")
    if not delete:
        print("Not deleting")
        raise typer.Abort()
    print("Deleting it!")


if __name__ == "__main__":
    typer.run(main)

As it's very common to abort if the user doesn't confirm, there's an integrated parameter abort that does it automatically

也就是自动 raise typer.Abort()

delete = typer.confirm("Are you sure you want to delete it?", abort=True)

使用 Rich 的 prompt​

import typer
from rich.prompt import Prompt


def main():
    name = Prompt.ask("Enter your name :sunglasses:")
    print(f"Hello {name}")


if __name__ == "__main__":
    typer.run(main)
