如何在Ruby中使用给定字符将字符串拆分为仅两部分? [英] How to split string into only two parts with a given character in Ruby?

问题描述

我们的应用程序正在从使用 Twitter 登录的人中挖掘姓名.

Our application is mining names from people using Twitter to login.

Twitter 在单个字符串中提供全名.

Twitter is providing full names in a single string.

示例

1. "Froederick Frankenstien"
2. "Ludwig Van Beethoven"
3. "Anne Frank"

我想根据第一个 " " 将字符串拆分为仅 两个 变量(first 和 last)(空格)找到.

I'd like to split the string into only two vars (first and last) based on the first " " (space) found.

Example    First Name    Last Name 
1          Froederick    Frankenstein
2          Ludwig        Van Beethoven
3          Anne          Frank

我熟悉 String#split 但我不确定如何只拆分一次.将接受最 Ruby-Way™(优雅)的答案.

I'm familiar with String#split but I'm not sure how to only split once. The most Ruby-Way™ (elegant) answer will be accepted.

推荐答案

String#split 接受第二个参数，即限制.

String#split takes a second argument, the limit.

str.split(' ', 2)

应该可以解决问题.
