如何互相添加列表的元素（StringType）

Question

我有一个这样的列表：

list1 = [["A","B","C"],["a","b","c"],["1","2","3"]]

如何将其转换为：

["Aa1","Bb2","Cc3"]

Answer 1

您可以使用zip和join：

list1 = [["A","B","C"],["a","b","c"],["1","2","3"]]

result = [''.join(s) for s in zip(*list1)]
print(result)

输出：

['Aa1', 'Bb2', 'Cc3']

Answer 2

将list与map一起使用，此处的密钥为Transpose list of lists

list(map(''.join,zip(*list1)))
['Aa1', 'Bb2', 'Cc3']
