Passo 49

Instruções

Antes de enviar os e-mails, adicione o idiom padrão do Python if __name__ == '__main__': seguido por uma chamada para main(). Isso garante que a função principal execute apenas quando o script for executado diretamente e não quando for importado como um módulo.

O que fazer:

Testes:

Você deve adicionar a verificação `if __name__ == '__main__':` fora da função `main`.
Você deve chamar `main()` dentro do bloco `if __name__ == '__main__':`.
