"Python's support for detecting and collecting garbage which involves "
"circular references requires support from object types which are "
"\"containers\" for other objects which may also be containers.  Types which "
"do not store references to other objects, or which only store references to "
"atomic types (such as numbers or strings), do not need to provide any "
"explicit support for garbage collection."
"O suporte do Python para detectar e coletar o lixo, que envolve referencias "
"circulares, requer suporte dos tipos de objetos que são \"contêineres\" para "
"outros objetos que também podem ser contêineres. Tipos que não armazenam "

"tipos atômicos (como números ou strings), não precisam fornecer nenhum "
"suporte explicito para coleta de lixo."
