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( \0 ^' K! ~1 S5 P+ i- W* ~- r
其中有一段如下
' U$ N. Q6 N z8 ^# M4 R) Cask turtles with [ infected? = true ] , }* z% g$ L1 i
我原本以为这句会回传『所有』infected? = true 的 turtle/ _+ Z& P5 L' o2 _% m( j8 A
但看结果似乎不是这样。4 O* g6 u: ~+ N% {& F
& e$ m, A3 j$ p. ]5 B3 H假设所有符合条件的有 5 笔) W3 p+ f+ S2 m
有时候回传 1 笔,有时回传 3 笔,是不固定的
4 Q% w+ q/ X% z5 ?1 V回头查语法定义& F! ^( b) A a# k" d7 c
with
/ L+ e2 T7 `( ]0 ]% C2 P0 nagentset with [reporter]
% T% A1 m0 I$ GTakes 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.4 A! u/ G2 ` L+ U
它只说回传 agents satisfying the given condition
, Y8 c& i q$ R4 g; m! F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 ?
& j* \4 F- q6 e$ @& K+ g+ a# U P3 Z: o% o
想确定一下
3 n$ \+ {3 x3 O: a0 X5 O谢谢!
