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
* g3 ^2 s! w: _% ^3 [其中有一段如下
0 Z" G+ U1 C5 I4 M% \0 D- gask turtles with [ infected? = true ]
, q. K Q# P" Z$ h( c我原本以为这句会回传『所有』infected? = true 的 turtle
0 \* ?5 A; z& P$ k# f9 @但看结果似乎不是这样。

假设所有符合条件的有 5 笔
: S5 F; l- d3 _* j5 f有时候回传 1 笔,有时回传 3 笔,是不固定的

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.
. l) F+ m$ X) m. N9 J它只说回传 agents satisfying the given condition3 N, g j6 n- K/ z( H" l
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 ? ' l4 H/ t' y* d( X; K9 U
