【LeetCode】520. Detect Capital【E】【83】

Given a word, you need to judge whether the usage of capitals in it is right or not.

We define the usage of capitals in a word to be right when one of the following cases holds:

1. All letters in this word are capitals, like "USA".
2. All letters in this word are not capitals, like "leetcode".
3. Only the first letter in this word is capital if it has more than one letter, like "Google".

Otherwise, we define that this word doesn't use capitals in a right way.

Example 1:

Input: "USA"
Output: True

Example 2:

Input: "FlaG"
Output: False

Note: The input will be a non-empty word consisting of uppercase and lowercase latin letters.

python对这个还是很友好的，哈哈哈，直接调用函数就行了

class Solution(object):
    def detectCapitalUse(self, word):
        return word.isupper() or word.islower() or word.istitle()
        '''
        if word.lower() == word or word.upper() == word or (word[0] == word[0].upper() and word[1:] == word[1:].lower()):
            return True
        return False
        '''
