如何+两个元组列表中的值

Question

如何从两个元组列表中添加元组以获取结果的新列表？

例如：

a = [(1,1),(2,2),(3,3)]   
b = [(1,1),(2,2),(3,3)]   

我们想得到

c = [(2,2),(4,4),(6,6)]  

我搜索谷歌并发现许多结果如何使用zip简单地添加两个列表，但找不到有关两个元组列表的任何内容。

Answer 1

使用zip两次和列表理解：

In [63]: a = [(1,1),(2,2),(3,3)]

In [64]: b = [(1,1),(2,2),(3,3)]

In [66]: [tuple(map(sum, zip(x, y))) for x, y in zip(a, b)]
Out[66]: [(2, 2), (4, 4), (6, 6)]

Answer 2

>>> a = [(1,1),(2,2),(3,3)]
>>> b = [(1,1),(2,2),(3,3)]
>>> [(i[0]+j[0], i[1]+j[1]) for i, j in zip(a,b)]
[(2, 2), (4, 4), (6, 6)]
