如何+兩個元組列表中的值

Question

如何從兩個元組列表中添加元組以獲取結果的新列表？

例如：

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

我們想得到

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

我搜索谷歌並發現許多結果如何使用zip簡單地添加兩個列表，但找不到有關兩個元組列表的任何內容。

Answer 1

使用zip兩次和列表理解：

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)]
