如何将上面一行中的最后一个（空格分隔的）字符串插入emacs中光标的当前行

Question

在python中工作时，我有时会发现我不必要地拥有一个代码片段：

thing = longfunctioncall(with, many, necessary, arguments, that, take, a, fairly, long, time, to, type)
formattedthing = [str(*q) for q in thing]

我可以合并到：

formattedthing = [str(*q) for q in longfunctioncall(with, many, necessary, arguments, that, take, a, fairly, long, time, to type)]

我知道你可以简单地杀死并猛拉整个声明，但我想知道是否有更多的EMACSy方法可以做到。
