0     1     1      0      0     0    1
0     1     0      1      0            


        

Answer 1

To change Dataframe into list use tolist() function to convert Let use say i have 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

df['column name'].values.tolist()

Answer 2

It looks like a transposed matrix:

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]]
