新手发问超简单问题,目前还处于研读范例码的阶段,边测边看结果来理解程序
- D) o5 I. L$ A3 G V1 a+ c2 C其中有一段如下
2 U h! r, \7 bask turtles with [ infected? = true ]
0 r, E. ^) \/ O# n& n2 X我原本以为这句会回传『所有』infected? = true 的 turtle
5 e- V8 x4 o' I- j: d但看结果似乎不是这样。

! |# l9 w' j4 Q# Q% a& s `假设所有符合条件的有 5 笔
. _& {# v* {" r% x有时候回传 1 笔,有时回传 3 笔,是不固定的
% D( J6 k& K. F: W0 ?& K回头查语法定义9 z# H! t$ D+ R0 c# G
with

Takes two inputs: on the left, an agentset (usually "turtles" or "patches"). On the right, a boolean reporter. Reports a new agentset containing only those agents that reported true -- in other words, the agents satisfying the given condition./ M+ p1 i4 ]5 P- \, J
它只说回传 agents satisfying the given condition
8 o' {0 A3 a; C/ p9 q* |( e是否 with 回传的是『符合条件』的数据,而不是『所有符合条件』的数据 ? 8 O) i0 W8 N9 B2 d7 C! J, P

想确定一下
