Doubt about the replace() method

Question

The replace() method is a method of the str class, correct?

Follows a code that 'rotates' perfectly where the object is an integer (or at least in my interpretation). Or in the case of interpolation this changes?

Follows:

def moeda(valor, moeda = 'R$'):
    return f'{moeda}{valor:.2f}'.replace('.', ',')


velocidade = float(input('Qual é a velocidade do carro? (KM) '))
if velocidade > 80:
    print('VELOCIDADE PERMITIDA ULTRAPASSADA!')
    print('\033[1;31mMULTADO!\033[m')
    multa = (velocidade - 80) * 6
    multa = moeda(multa)
    print(f'Você foi multado em {multa}')
else:
    pass

PS. The currency() function transforms an integer number into a currency format, replacing integer points with commas.

Answer 1

As you said yourself, replace is a string and value method of the type int or float nay possess him.

What happens in your code is that you pass the value into a new string using string formatting f-string. So you are using the method replace of a str created in the format and not a numeric value. See the example below:

valor = 75.99
string_valor = f"R$ {valor}"

print(type(string_valor), "-", string_valor)  # <class 'str'> - R$ 75.99

string_valor = string_valor.replace(".", ",")
print(string_valor)
