I was trying to write a click option argument with type=click.Choice((“North”,
“South”, “West”, “East”)) and I also like to annotate the function itself for
documentation (even though I call it without passing arguments). Something like
the the following..
@click.command()
@click.option(“--direction”, type=click.Choice((“North”, “South”, “West”,
“East”)), default=“North”)
def main(direction: “North” | “South” | “West” | “East” = “North”) -> None:
print(direction)
