我面臨一個奇怪的問題，我在資料框中有一個列名“視窗”，它有一個值串列，即 [3,9,45,78]。我正在嘗試使用 df.explode('window') 來分解此列，但這不起作用。“視窗”列的資料型別是物件。我檢查了我的熊貓版本 - 1.3.4
資料框示例
uj5u.com熱心網友回復：
請記住，df.explode它不會在適當的地方完成它的作業。它回傳一個帶有更改的新資料框：
import pandas as pd
data = [
[ 0, [1,2,3], [4,5,6], 7 ],
[ 0, [1,2,3], [4,5,6], 7 ],
[ 0, [1,2,3], [4,5,6], 7 ],
[ 0, [1,2,3], [4,5,6], 7 ],
[ 0, [1,2,3], [4,5,6], 7 ]
]
df = pd.DataFrame( data, columns=['one', 'two','three','four'] )
print(df)
df2 = df.explode('two')
print(df2)
輸出：
one two three four
0 0 [1, 2, 3] [4, 5, 6] 7
1 0 [1, 2, 3] [4, 5, 6] 7
2 0 [1, 2, 3] [4, 5, 6] 7
3 0 [1, 2, 3] [4, 5, 6] 7
4 0 [1, 2, 3] [4, 5, 6] 7
one two three four
0 0 1 [4, 5, 6] 7
0 0 2 [4, 5, 6] 7
0 0 3 [4, 5, 6] 7
1 0 1 [4, 5, 6] 7
1 0 2 [4, 5, 6] 7
1 0 3 [4, 5, 6] 7
2 0 1 [4, 5, 6] 7
2 0 2 [4, 5, 6] 7
2 0 3 [4, 5, 6] 7
3 0 1 [4, 5, 6] 7
3 0 2 [4, 5, 6] 7
3 0 3 [4, 5, 6] 7
4 0 1 [4, 5, 6] 7
4 0 2 [4, 5, 6] 7
4 0 3 [4, 5, 6] 7
