Ruby字符串操作（分隔符）

Question

我有一个这样的字符串：

14.015_KNECHT_178178

如何分割它：

art = 14.015
man = KNECHT

如您所见，分隔符为_。

Answer 1

string＃split可以做到这一点。

>> (art,man,foo) = "14.015_KNECHT_178178".split '_'
=> ["14.015", "KNECHT", "178178"]
>> p art
"14.015"
=> "14.015"
>> p man
"KNECHT"
=> "KNECHT"
>> p foo
"178178"
=> "178178"

Answer 2

试试这个

art,man= "14.015_KNECHT_178178".split(/_/)
