导读：输入： "The boy is running on the train" 预期产量： ["The boy","boy is","is running","running on","on the","the train"] 在python中实现这一目标的最简单方法是什么？解决方法你拆分所有空格,然后重新加入对： words = inputstr.split()secondwords

输入：

"The boy is running on the train"

预期产量：

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

在python中实现这一目标的最简单方法是什么？

解决方法

你拆分所有空格,然后重新加入对：

words = inputstr.split()
secondwords = iter(words)
next(secondwords)

output = [' '.join((first,second)) 
          for first,second in zip(words,secondwords)]

演示：

>>> inputstr = "The boy is running on the train"
>>> words = inputstr.split()
>>> secondwords = iter(words)
>>> next(secondwords)  # output is ignored
'The'
>>> [' '.join((first,second)) for first,secondwords)]
['The boy','boy is','is running','running on','on the','the train']
