内置方案以检查列表是否包含 [英] Scheme built-in to check list containment

问题描述

在Python中，我可以执行列表中的x"以查看列表中是否包含x. Scheme中是否有任何等效的内置功能可以做到这一点?

In Python I can do "x in list" to see if the list contains x. Is there any equivalent built-in in Scheme to do this?

推荐答案

R5RS 和R6RS

The R5RS, and the R6RS standard library for lists define memq, memv, and member which can be used for that purpose.
