如何在 python 中按顺序附加两个列表？

Question

我有一个坐标列表和另一个高度值列表。如何按顺序将高度值附加到坐标列表？

coor = [[[83.75, 18.70], [57.50, 18.70], [57.5, 2.87], [83.75, 4.18]],
   [[83.75, 34.54], [110.0, 35.0], [104.86, 19.59], [83.75, 19.59]],
   [[104.86, 19.59], [83.75, 19.59], [83.75, 4.18], [100.0, 5.0]],
   [[-5.0, 33.0], [18.12, 33.40],[18.12, 16.70],[-2.53, 16.70]], 
   [[18.12, 16.70],[-2.53, 16.70], [0.0, 0.0],[18.12, 0.90]]]
height = [5,4,5,6,6]

预期结果：

result = [[[83.75, 18.70], [57.50, 18.70], [57.5, 2.87], [83.75, 4.18],5],
   [[83.75, 34.54], [110.0, 35.0], [104.86, 19.59], [83.75, 19.59],4],
   [[104.86, 19.59], [83.75, 19.59], [83.75, 4.18], [100.0, 5.0],5],
   [[-5.0, 33.0], [18.12, 33.40],[18.12, 16.70],[-2.53, 16.70],6], 
   [[18.12, 16.70],[-2.53, 16.70], [0.0, 0.0],[18.12, 0.90],6]]

Answer 1

如果你不介意元组，你可以使用zip

> list(zip(coor, height))

[([[83.75, 18.7], [57.5, 18.7], [57.5, 2.87], [83.75, 4.18]], 5),
 ([[83.75, 34.54], [110.0, 35.0], [104.86, 19.59], [83.75, 19.59]], 4),
 ...

如果它必须是一个列表，请在理解中使用 zip。

> [list(pair) for pair in zip(coor, height)]

[[[83.75, 18.7], [57.5, 18.7], [57.5, 2.87], [83.75, 4.18]], 5],
[[[83.75, 34.54], [110.0, 35.0], [104.86, 19.59], [83.75, 19.59]], 4],
...

Answer 2

tldr：一行解决方案，zip 可迭代对象（Python docs）和下面列出的所需输出说明：

[list(item) for item in list(zip(coor,height))]

解释：

list1 = [ 
    [['a','a'],['aa','aa']], 
     [['b','b'],['bb','bb']]]
list2 = [1,2]

for item in list(zip(list1,list2)): 
    print('zip output', item) 
    print('desired output', list(item))

输出：

zip output ([['a', 'a'], ['aa', 'aa']], 1)
desired output [[['a', 'a'], ['aa', 'aa']], 1]
zip output ([['b', 'b'], ['bb', 'bb']], 2)
desired output [[['b', 'b'], ['bb', 'bb']], 2]

作为一行列表理解：

[list(item) for item in list(zip(list1,list2))]

输出：

[[[['a', 'a'], ['aa', 'aa']], 1], [[['b', 'b'], ['bb', 'bb']], 2]]
