Question

我试图组合多个元组，但不知道如何。我知道如何创建一个元组，但我不太确定如何将它们组合在一起。我想继续追加（实际上不是附加因为我不想要一个列表）。我从每一行中拉出一根弦并将所有元组放在一起

x = (132, 534, 4)
y = (345, 531, 1)
z = (212, 421, 5)

我想要的回复

(132, 534, 4), (345, 531, 1), (212, 421, 5)

Answer 1

您的示例中的元组可以像这样创建：

>>> # The following line is equivalent to:  new_tuple = (x, y, z)
>>> new_tuple = x, y, z
>>> new_tuple
((132, 534, 4), (345, 531, 1), (212, 421, 5))
>>>

但是，因为元组是不可变的（创建后无法更改）序列，所以每次要“追加”它时都需要创建一个新元素：

>>> new_tuple = x, y, z
>>> new_tuple
((132, 534, 4), (345, 531, 1), (212, 421, 5))
>>> w = 1, 2, 3  # This is another tuple that needs to go inside new_tuple
>>> new_tuple = x, y, z, w  # So, we have to rebuild new_tuple to include it
>>> new_tuple
((132, 534, 4), (345, 531, 1), (212, 421, 5), (1, 2, 3))
>>>

这就是为什么最好只使用一个列表，它是一个可变的（可以在创建后更改）序列，它具有append方法：

>>> new_list = [x, y, z]  # Square brackets make a list
>>> new_list
[(132, 534, 4), (345, 531, 1), (212, 421, 5)]
>>> w = 1, 2, 3
>>> new_list.append(w)  # Add w to new_list without rebuilding it
>>> new_list
[(132, 534, 4), (345, 531, 1), (212, 421, 5), (1, 2, 3)]
>>>

Answer 2

最简单的方法可能是这个

x = (132, 534, 4)
y = (345, 531, 1)
z = (212, 421, 5)

r = x, y, z

如何将元组附加在一起？
