如何在元组中单独添加元素?

How to add elements individually within the tuple?

例如，我需要(0,1) + (2,3)中的(2, 4)，我一直在这样做，但是有没有更多的pythonic/更少冗长的方法来做到这一点?

For example, i need (2, 4) from (0,1) + (2,3), I've been doing it as such but is there a more pythonic / less verbose way to do the same?

>>> x = (0,1)
>>> y = (2,3)
>>> x + y
(0, 1, 2, 3)
>>> tuple(i+j for i,j in zip(x,y))
(2, 4)

推荐答案

您可以在此处使用zip和sum:

示例:

>>> x = (0, 1)
>>> y = (2, 3)
>>> tuple(map(sum, zip(x, y)))
(2, 4)

• zip让我们成对地组合两个可迭代对象或列表的元素.
• sum让我们对这些对求和
• map让我们每对应用sum函数.
• 最终，我们将结果列表(在Python 3.x中为或可迭代的)转换回tuple，因为这似乎是您想要的.
• zip lets us combine elements of two iterables or lists in pairs.
• sum lets us sum the pairs
• map lets us apply the sum function per pair.
• finally we convert the resulting list (or iterable in Python 3.x) back into a tuple since that's what you seem to have wanted.

上面的例子基本上以"

(0 + 2, 1 + 3)
