仅仅因为a [i]是元组，您会收到一个错误，您不能直接添加元组.您必须访问它们，实现这一目标的更Python方式是:

You're getting an error just because the a[i] are tuples, you can't add directly tuple. You have to access them, a more pythonic way to achieve this would be:

map(sum, zip(*a))

zip函数可以完全满足您的需求，之后您必须根据需要处理每个条目，在您使用sum的情况下，您还可以尝试以下操作:

the zip function do exactly what you're looking for, after that you have to process each entry according to what you need, in your case sum , you can also try this:

result = []
for elem in zip(*a):
    result.append(sum(elem))
