145. 大小写转换

思路

将一个字符由小写字母转换为大写字母
样例
    a -> A
    b -> B

Python

class Solution:
    """
    @param character: a character
    @return: a character
    """

    def lowercaseToUppercase(self, character):
        # write your code here
        return character.upper()


if __name__ == "__main__":
    s = Solution()
    n = 'a'
    print(s.lowercaseToUppercase(n))
    n = 'b'
    print(s.lowercaseToUppercase(n))
