# Note     : 请实现一个函数，将一个字符串中的空格替换成“%20”。例如，当字符串为We Are Happy.则经
#            过替换之后的字符串为We%20Are%20Happy。


class Solution:

    # s 源字符串
    @staticmethod
    def replace_space(s):
        # write code here
        return s.replace(" ", "%20")


def main():
    text = "We Are Happy"
    new_text = Solution.replace_space(text)
    print(new_text)

if __name__ == '__main__':
    main()
