一些建议的改进:

1. while循环将永远运行，您应该删除它.
2. 使用max和生成器表达式以节省内存的方式生成最长的单词.

3. 您应生成一个长度大于40个字符的句子列表，其中包括具有列表理解的longestWord.这也应该从while循环中删除，因为它只会发生.

1. The while loop will run forever, you should probably remove it.
2. Use max and generator expressions to generate the longest word in a memory-efficient manner.

3. You should generate a list of sentences with a length greater than 40 characters that include longestWord with a list comprehension. This should also be removed from the while loop, as it only happens.

已发送= [" ".join(sent) for sent in listOfSents if longestWord in sent and len(sent) > 40]

如果要打印出以随机顺序找到的每个句子，则可以尝试改组刚刚创建的列表:

If you want to print out every sentence that is found in a random order, then you could try shuffling the list you just created:

for sent in random.shuffle(sents): print sent

这是这些更改后代码的外观:

This is how the code could look with these changes:

import nltk
from nltk.corpus import gutenberg
from random import shuffle

listOfSents = gutenberg.sents()
triggerSentence = raw_input("Please enter the trigger sentence: ")

longestWord = max(triggerSentence.split(), key=len)
longSents = [" ".join(sent) for sent in listOfSents 
                 if longestWord in sent 
                 and len(sent) > 40]

for sent in shuffle(longSents):
    print sent
