如何以以下格式创建熊猫数据框：
A B C D
0 [1,2,3,4] [2,3,4,5] [4,5,5,6] [6,3,4,5]
1 [2,3,5,6] [3,4,6,6] [3,4,5,7] [2,6,3,4]
2 [8,9,6,7] [5,7,9,5] [3,7,9,5] [5,7,9,8]
基本上每一行都有一个列表作为元素。我正在尝试使用机器学习对数据进行分类。每个数据点有 40 x 6 个值。是否有任何其他格式适合输入分类器。

# Number of sample in one shot
samples_per_shot = 40
# Calculate number of shots in dataframe
