### [leetCode] 884. Uncommon Words from Two Sentences (Python)

사용자 솜씨좋은장씨 2020. 7. 31. 21:24

We are given two sentences A and B.  (A sentence is a string of space separated words.  Each word consists only of lowercase letters.)

A word is uncommon if it appears exactly once in one of the sentences, and does not appear in the other sentence.

Return a list of all uncommon words.

You may return the list in any order.

Example 1:

``````Input: A = "this apple is sweet", B = "this apple is sour"
Output: ["sweet","sour"]``````

Example 2:

``````Input: A = "apple apple", B = "banana"
Output: ["banana"]``````

Note:

1. 0 <= A.length <= 200
2. 0 <= B.length <= 200
3. A and B both contain only spaces and lowercase letters.

Solution

``````from collections import Counter

class Solution:
def uncommonFromSentences(self, A: str, B: str) -> List[str]:
array = A.split(" ") + B.split(" ")

cnt = list(Counter(array).items())

answer = [item for item in cnt if item == 1]
