Validation of cpf field

[Luandersonsouza]

I've made a few change this lines bellow:

cpf = StringField("CPF", validators=[DataRequired(message="O CPF é obrigatório"), self.cpf_validator])

def __verify_cpf(self):
        cpf = ''.join(filter(str.isdigit, cpf)) #Elimina caracteres não numéricos
        if len(cpf) != 11:
            return False

        def calcular_digito(cpf, peso):
        soma = sum(int(digit) * peso for digit, weight in zip(cpf, peso))
        digito = 11 - soma % 11
        return '0' if digito > 9 else str(digito)

    #dígitos verificadores
    peso1 = range(10, 1, -1)
    peso2 = range(11, 2, -1)

    dv1 = calcular_digito(cpf[:9], peso1)
    dv2 = calcular_digito(cpf[:9] + dv1, peso2)

    return cpf[-2:] == dv1 + dv2

    def __cpf_validator(self, form, field):
        if not forms.__verify_cpf(field.data):
            raise ValidationError('CPF inválido')

And i created a group of functions to verify the cpf field, tests are needed to check conflict.
