|the sonnets |
| |
|by william shakespeare |

| |
|1 |
|from fairest creatures we desire increase |
|that thereby beautys rose might never die |
|but as the riper should by time decease |
|his tender heir might bear his memory |
|but thou contracted to thine own bright eyes |
|feedst thy lights flame with selfsubstantial fuel|

shakeWordsDF = (shakespeareDF.select(explode(split(shakespeareDF[0],"\s+"))
我想了解：
