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
Q1 a. u1 |% B其中有一段如下
, l& w$ X8 T/ p/ w' S4 u- @1 E8 }( S2 Kask turtles with [ infected? = true ] & B- j4 x' G' d8 X
我原本以为这句会回传『所有』infected? = true 的 turtle
4 D8 s/ C# Y) H6 |: s- x5 j但看结果似乎不是这样。
' f8 v B) M0 a% q- z
$ z7 K8 c, X- l4 }! Z* c \& q7 I假设所有符合条件的有 5 笔
. [* q9 D# }( u有时候回传 1 笔，有时回传 3 笔，是不固定的
1 o0 s& X G( x* ]6 l3 o回头查语法定义
g# P4 Q8 K+ N# M& ~: iwith
* j- C9 n N& d' Uagentset with [reporter]2 v8 h8 O5 F' N0 Z. z0 K4 T
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.
* g5 p5 c! v6 v3 {. {9 \它只说回传 agents satisfying the given condition
4 t7 O& h' S5 _, U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 ?
- s" q2 I9 a6 {9 J B
% J6 E5 y, u" a" p想确定一下
8 K7 k6 q% `7 s+ l2 e; I谢谢！7 {5 E) Z8 A: ^6 y3 c2 {( W
