將列表轉換為數據框（熊貓）

Question

有什么辦法可以將這種類型的輸出轉換為 Dataframe 嗎？ 輸出：

[['A', 'B'], ['Orange', 'Apple']]
[['C', 'D'], ['Coconut', 'Lemon']]
[['E'], ['Mango', 'Strawberry']]

I want to turn the output into a dataframe like this:

`     x1         X2
0   A,B   Orange, Apple
1   C,D   Coconut, Lemon
2   E     Mango, Strawberry`

Answer 1

只需將此數據添加到列表中

import pandas as pd

data = [[['A', 'B'], ['Orange', 'Apple']],
        [['C', 'D'], ['Coconut', 'Lemon']],
        [['E'], ['Mango', 'Strawberry']]]

df = pd.DataFrame(data, columns=['x1', 'x2'])

所以 df 看起來像

       x1                   x2
0  [A, B]      [Orange, Apple]
1  [C, D]     [Coconut, Lemon]
2     [E]  [Mango, Strawberry]

Answer 2

如果您的起始數據在列表中，並且您想用逗號連接每個列表，這應該有效：

l = [[['A', 'B'], ['Orange', 'Apple']],
    [['C', 'D'], ['Coconut', 'Lemon']],
    [['E'], ['Mango', 'Strawberry']]]

df = pd.DataFrame([[', '.join(v) for v in i] for i in l],columns = ['x1','x2'])

stack()和str.join()也是一個選項：

df = pd.DataFrame(l,columns = ['x1','x2']).stack().str.join(', ').unstack()

輸出：

     x1                 x2
0  A, B      Orange, Apple
1  C, D     Coconut, Lemon
2     E  Mango, Strawberry

Answer 3

簡單修復：

pd.DataFrame(
    {"x1":[["A", "B"], ["C", "D"], ["E"]],
    "x2":[["Orange", "Apple"], ["Coconut", "Lemon"], ["Mango", "Strawberry"]]}
)
