原标题:Ruby To Python Syntax Confusion

我试图将某人的鲁比法改成我的斯勒法。 最初的开发商不再与我们合作,我不知道Ruby。 他的多数法典是容易遵循的,但下面的一些辛迪加正在赶上我。

例:

                myTable =   
                myTable << [ 0, 1, 0, 0, 0, 300].pack( vvvvvv )
                myTable [40, 4] = [41310005 - 5].pack( V )

(1) 我正确地认为,在第二行之后,我的手法将包含[]中具体指明的六种数值? 而且,. Pack() similar to struct. Pack/code>?

2) 在第三行之后,将储存在阵列第40位的权利价值是4倍? []5岁的人只是 f,还是具有某种特殊意义?

最佳回答

您对第二行有误,但奇怪的是,你认为第二行与<条码>truct. Pack相似。 <代码>Array# Pack(>> 回归包装数据(例如struct. Pack)和String#<< 附录一至接收方英尺。 第三行按指数40排列的4个字体为<代码>[41310000]. 包装(V )的结果。

问题回答

查阅http://ruby-doc.org/french/sc/presidencyes/Array.html#M002222” rel=“nofollow noreferer”>Array# Pack。 它把一个阵列变成了双体序列的显示。 <代码>v为“Short, Littleendian byte Order”,V为“Long, Littleendian byte Order”。

<< 发送至<编码>St物体时,作为分类。 由于胎体在这一点之前是空洞的,但myTable本可立即推入[0、1、0、0、300](vvvvvvv )

http://ruby-doc.org/french/classes/String.html#M000772"rel=“nofollow noreferer”>String#[m,n]= 替换索引mm+n

简言之,直言之明(它被赋予了直面字面)。 The <<mente strings(和阵列)的操作者是护卫者,因此,你把护卫放在了护卫上。 包装法回收了一种扼杀,在这种情况下,是“Short, Littleendian byte Order”。 它有6个短小的愤怒,没有以任何方式转换为ASCII, 只是被丢在地狱中。

之后,这种按原样分类的群种的一部分被包装的另一种价值所取代,这反过来又使“Long,甚微的安定”重新回归。 它被长篇的40个用tes子取代,4个用.子取代。

这是一些粗体弱的代码。 仅仅知道,我的手法是一种扼杀,该包裹是按原样返回的。
