如何让该题的要输入的正则表达式部分简洁一些
这是一道题目,我的答案见下文怎么才能更加简洁呢?{:301_999:}
# d) Correct the given RE to get the expected output.
words = 'plink incoming tint winter in caution sentient'
change = re.compile(r'int|in|ion|ing|inco|inter|ink')
# wrong output
change.sub(r'X', words)
# 返回 'plXk XcomXg tX wXer X cautX sentient'
# expected output
change = re.compile('|'.join(sorted(['int','in','ion','ing','inco','inter','ink'], key=len, reverse=True))) ##### add your solution here
print(change.sub(r'X', words))
# 返回 'plX XmX tX wX X cautX sentient' `i(n(|(co)|(ter))?)|(on)`楼主试试! 哈哈衬 发表于 2020-5-18 13:39
`i(n(|(co)|(ter))?)|(on)`楼主试试!
返回的结果是:plX XmX tX wXer X cautiX sentient
要求是: 返回 'plX XmX tX wX X cautX sentient'
好像哪里不对{:301_998:} re.sub(r'i(n(|(co)|t(?:er)*)*|(on))','X',words) airdge 发表于 2020-5-18 15:40
