NetLogo:如何对列表执行多项操作(查找，获取，替换，删除，搜索列表中的元素，....) [英] NetLogo : How to do multiple operations on lists (find, get , replace, remove , search elements within lists , ....)

问题描述

我是NetLogo的新手，我想知道是否有完整的参考资料来对列表进行操作，除了Netlogo词典以外，我还阅读了此处的大多数文章，但是例如，如果我需要像这样的数字对列表，

I am new to NetLogo and I was wondering if there is a complete reference to do operations on lists, I have read most of the posts here in addition to Netlogo dictionary but for example if I need a list of pairs of numbers like

[[1 2] [2 2] [2 3] ,,, ] 

搜索时

member? 3 thislist 

我是否可以选择说要考虑进行搜索的内部列表中的哪个元素?例如，如果搜索第一个元素，我将得到false；如果搜索第二个元素，我将为true.

Will I have the option to say which element of inner list I am considering for the search ? for instance I will get false if it search first element and true if I search second element.

有人可以澄清Netlogo中列表的使用吗?

Can anybody please clarify the use of lists in Netlogo?

推荐答案

map，filter，reduce，foreach，n-values和sort-by使用任务在列表上提供可自定义的操作.请参见 http://ccl.northwestern.edu/netlogo/docs/programming.html#任务.

map, filter, reduce, foreach, n-values, and sort-by provide customizable operations on lists, using tasks. See http://ccl.northwestern.edu/netlogo/docs/programming.html#tasks.

这是您使用map的示例:

observer> show member? 3 map first [[1 2] [2 2] [2 3]]
observer: false
observer> show member? 3 map last [[1 2] [2 2] [2 3]]
observer: true
