Question

输入:

"The boy is running on the train"

预期输出:

["The boy", "boy is", "is running", "running on", "on the", "the train"]

在 python 中实现这个最简单的解决方案是什么。

Answer 1

line="The boy is running on the train"
words=line.split()
k=[words[index]+' '+words[index+1] for index in xrange(len(words)-1)]
print k
