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
! F9 }2 i% l+ V% ~- |: p其中有一段如下
" J: N) Q0 ]# z- l* ~ask turtles with [ infected? = true ]
6 |9 M3 C8 Z6 l2 S4 h# R% S我原本以为这句会回传『所有』infected? = true 的 turtle
; _# k' b# I& J% [4 m9 v+ m但看结果似乎不是这样。# J) a0 w& r- r) B' ~
" U7 g! m5 ]7 t" `, ?3 E! i
假设所有符合条件的有 5 笔* |: ]+ i8 S8 X% l) p8 u
有时候回传 1 笔，有时回传 3 笔，是不固定的, n) G9 `) S7 i: k0 N) s- `7 ]
回头查语法定义" X4 M, z3 y7 t
with / F, m& g) I: B$ |# g+ N, f
agentset with [reporter]- B% ~9 O+ l z- H. Y
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.: Q) `* f: }+ m# _& U w/ T* B7 k
它只说回传 agents satisfying the given condition
6 r& Q# y0 E H2 G, t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 ?
. c/ |# b* ~1 o- F4 j' i+ r: P5 b/ {1 F' B4 q/ V- c
想确定一下
' U, O7 D: r" J% |, a谢谢！/ V4 Z$ c Z& L
