Se quando rodar o _script_ do _servidor ao vivo_ você pega um erro sobre linguagem não suportada, alguma coisa como:

Como o editor conhece os tipos de variáveis, você não obtém apenas o preenchimento automático, mas também as verificações de erro:

Agora você sabe que precisa corrigí-lo, converta `age` em uma string com `str(age)`:
