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! f! ?3 u! e S/ U
其中有一段如下
# m2 [) h, o. c+ u) Dask turtles with [ infected? = true ]
: I0 \ O3 J& ?& ]' [我原本以为这句会回传『所有』infected? = true 的 turtle- V5 A, x; W5 r. @
但看结果似乎不是这样。( I) a/ }8 ]5 f) B( R
6 a1 @1 ~$ c6 V. b) Z, p. P; Z' z6 M
假设所有符合条件的有 5 笔: a# m' `( H5 y
有时候回传 1 笔,有时回传 3 笔,是不固定的
7 D6 t& l" A% c) {2 [) |回头查语法定义3 T0 C$ H# l( `- A N, `3 p
with
6 m) m/ c& k6 {8 N. Y: m0 magentset with [reporter]
! N! d2 d* b/ a' Z$ |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.# Z$ O* b/ `' B8 c9 W; f
它只说回传 agents satisfying the given condition! r% G% l5 U& J( f G
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 ? , q% d% \( M* |' @% Y
7 K' z, D7 n* O N1 @. W
想确定一下
7 _% B! j. {$ a" x$ v2 U谢谢!
