numbers

Numbers work in the same unsurprising way as strings with the difference that they are parsed into the correct type.

Int

Integers can be passed in any string format accepted by int and will raise an error in case that fails, for example, 42.0 won't be accepted.

import platitudes as pl


def age_guesser(age: int):
    if age == 42:
        print("You guessed right!")
    else:
        print("Try again!")


pl.run(age_guesser)

Float

Same applies to float, but in this case the parsing is performed by float so all of 42, 42.0 and 42e0 would be acceptable.

import platitudes as pl


def calculate_vat(price: float):
    taxed_price = price * 1.2
    print(f"The new price is {taxed_price}")


pl.run(age_guesser)

Of course both integers and float may take a default value turning them into optional parameters.
