Crie uma função para aplicar desconto - Criar uma função Apply Discount

[luizao4k]

Conte-nos o que está acontecendo:

Quando apply_discount é chamado com um price (primeiro argumento) que não é um número (int ou float) ele deve retornar The price should be a number.

Seu código até o momento

def verificar_preco(x):
    if type(x) is bool or type(x) is str:
        return "The price should be a number."
    if x < 0:
        return "The price should be greater than 0."
    return True
def verificar_desconto(y):
    if type(y) is bool or type(y) is str:
        return "The discount should be a number."
    if y < 0 or y > 100:
        return "The discount should be between 0 and 100."
    return True
def apply_discount(price, discount):
    ver1 = verificar_preco(price)
    ver2 = verificar_desconto(discount)
    
    if ver1 is True and ver2 is True: 
        x = (discount * price) / 100
        final = price - x
        print(f"Success! Final price: {final}")
        return final
    else:
     
        if type(ver1) is str:
            print(f"Error (Price): {ver1}")
        if type(ver2) is str:
            print(f"Error (Discount): {ver2}")
    print("-" * 30)

apply_discount(100, 20)
apply_discount(200, 50)
apply_discount(50, 100)
apply_discount(74.5, 20)
apply_discount(True, 20)
apply_discount(-5, 20)
apply_discount(5, -20)

Welcome to the forum @luizao4k,

I highly recommend writing all of your code within one function.

@luizao4k

if type(x) is bool or type(x) is str:

What if price is in a list or a tuple or a set…? Does your code handle that?

Please take a look at how to use isinstance to check for multiple types at the end of this query lecture:

Understanding Variables and Data Types - How Do the type() and isinstance() Functions Work? | Learn | freeCodeCamp.org

@luizao4k

return "The price should be a number."

Should your validation messages have punctuation?

You can see what your function returns by wrapping your function calls in print().

Happy coding
