How can I convert columns of a pandas DataFrame into a list of lists?
提问by naz
I have a pandas DataFrame with multiple columns.
我有一个包含多列的 Pandas DataFrame。
2u 2s 4r 4n 4m 7h 7v
0 1 1 0 0 0 1
0 1 0 1 0 0 1
1 0 0 1 0 1 0
1 0 0 0 1 1 0
1 0 1 0 0 1 0
0 1 1 0 0 0 1
What I want to do is to convert this pandas.DataFrameinto a list like following
我想要做的是将其转换pandas.DataFrame为如下列表
X = [
[0, 0, 1, 1, 1, 0],
[1, 1, 0, 0, 0, 1],
[1, 0, 0, 0, 1, 1],
[0, 1, 1, 0, 0, 0],
[0, 0, 0, 1, 0, 0],
[0, 0, 1, 1, 1, 0],
[1, 1, 0, 0, 0, 1]
]
2u 2s 4r 4n 4m 7h 7v are column headings. It will change in different situations, so don't bother about it.
2u 2s 4r 4n 4m 7h 7v 是列标题。它会在不同的情况下发生变化，所以不要理会它。

It looks like a transposed matrix:
它看起来像一个转置矩阵：
df.values.T.tolist()
[list(l) for l in zip(*df.values)]
[[0, 0, 1, 1, 1, 0],
[1, 1, 0, 0, 0, 1],
[1, 0, 0, 0, 1, 1],
[0, 1, 1, 0, 0, 0],
[0, 0, 0, 1, 0, 0],
[0, 0, 1, 1, 1, 0],
[1, 1, 0, 0, 0, 1]]

要将 Dataframe 更改为列表，请使用 tolist() 函数进行转换假设我有 Dataframe df
to change into list you can simply use tolist() function

df.values.tolist()
You can also change a particular column in to list by using
