Verifique esta função, ela já possui type hints:

{* ../../docs_src/python_types/tutorial003.py hl[1] *}

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)`:
