Python itertools.zip_longest(*iterables, fillvalue=None)

创建一个迭代器，从每个可迭代对象中收集元素。如果可迭代对象的长度未对齐，将根据 fillvalue 填充缺失值。

from itertools import zip_longest


class Solution:
    def mergeAlternately(self, word1: str, word2: str) -> str:
        return ''.join(a + b for a, b in zip_longest(word1, word2, fillvalue=''))


print(Solution().mergeAlternately(word1="abcd", word2="pq"))
