Question

我有一个由2个浮点数的4个列表组成的2个列表，例如：

L1 = [ [0,1], [3,4], [2,5], [4,1] ] 
L2 = [ [4,3], [3,5], [2,2], [1,3] ]

我如何将其重塑为：

L_combined = [[L1 first index of each sublist],
              [L2 first index of each sublist],
              [L1 second index of each sublist],
              [L2 second index of each sublist]]

要清楚，这应该导致：

[[0,3,2,4], 
 [4,3,2,1],
 [1,4,5,1], 
 [3,5,2,3]]

对于合并的一般情况，我该怎么做：

L1 = [[1, 2, .. Y], [1, 2, .. Y] ...]
L2 = [[1, 2, .. Y], [1, 2, .. Y] ...]
...
LX = [[1, 2, .. Y], [1, 2, .. Y] ...]

进入

L_combined = [[L1 first index of each sublist],
              [L2 first index of each sublist],
              [....]
              [....],
              [LX Yth index of each sublist]]

谢谢！

Answer 1

您可以使用：

output = [[i[0] for i in list1], [i[0] for i in list2], [i[1] for i in list1], [i[1] for i in list2]]

您可以使用：

lsts = [lst1, lst2, lst3 ...]

output = [[j[k]  for j in i] for k in range(len(lsts[0][0])) for i in lsts]

这是假设所有列表都相同

输入：

lst1 = [['a11', 'a21', 'a31'],['a12', 'a22', 'a32'],['a13', 'a23', 'a33']]
lst2 = [['b11', 'b21', 'b31'],['b12', 'b22', 'b32'],['b13', 'b23', 'b33']]
lst3 = [['c11', 'c21', 'c31'],['c12', 'c22', 'c32'],['c13', 'c23', 'c33']]

输出：

[['a11', 'a12', 'a13'], ['b11', 'b12', 'b13'], ['c11', 'c12', 'c13'], ['a21', 'a22', 'a23'], ['b21', 'b22', 'b23'], ['c21', 'c22', 'c23'], ['a31', 'a32', 'a33'], ['b31', 'b32', 'b33'], ['c31', 'c32', 'c33']]
