Question

问题是，当我的句子中包含两个字母相同的单词时，如何让程序在阅读时给我第一个最长的单词而不是两个单词？

import sys 

inputsentence = input("Enter a sentence and I will find the longest word: ").split()
longestwords = []
for word in inputsentence:
    if len(word) == len(max(inputsentence, key=len)):
        longestwords.append(word)

print ("the longest word in the sentence is:",longestwords)

示例：快速的棕色狐狸......现在程序给我“快速”和“棕色”，如何调整我的代码只是给我“快速”，因为它是第一个最长的单词？

Answer 1

我会完全摆脱for-loop而只是这样做：

>>> mystr = input("Enter a sentence and I will find the longest word: ")
Enter a sentence and I will find the longest word: The quick brown fox
>>> longest = max(mystr.split(), key=len)
>>> print("the longest word in the sentence is:", longest)
the longest word in the sentence is: quick
>>>

Answer 2

只需打印列表中的第一个：

print ("the longest word in the sentence is:",longestwords[0])

可能有更好的方法可以做到这一点，但这需要对代码进行最少的修改。

Answer 3

为什么不呢：

longest_word = None

for word in inputsentence:
    if len(word) == len(max(inputsentence, key=len)):
        longest_word = word

print ("the longest word in the sentence is:",longest_word)

Answer 4

更多pythonic方式

import sys 

inputsentence = input("Enter a sentence and I will find the longest word: ").split()
# use function len() as criteria to sort
inputsentence.sort(key=len)
# -1 is last item on list
print ("the longest word in the sentence is:", sentence[-1])
