Good afternoon. I would like to know how to declare and use methods within the same class. For example, in a class there are 2 methods, which 1 method uses the other.

For example:

class ClasseEMetodo:
    def retorna_valor:
        return '10'

    def imprimi_valor:
        print('O valor é {0}' retorna_valor())


# chamada
var = ClasseEMetodo
var.imprimi_valor()

The error shown is:

    def retorna_valor:
                     ^
SyntaxError: invalid syntax
