Turning a matrix to dummy matrix
0
I've generated a list of combination and would like to turn it into "dummies" matrix
import pandas as pd
from itertools import combinations
comb = pd.DataFrame(list(combinations(range(1, 6), 4)))
0 1 2 3
0 1 2 3 4
1 1 2 3 5
2 1 2 4 5
3 1 3 4 5
4 2 3 4 5
would like to turn the above dataframe to a dataframe look like below. Thanks.

You can use MultiLabelBinarizer:
from sklearn.preprocessing import MultiLabelBinarizer
lb = MultiLabelBinarizer()
df = pd.DataFrame(lb.fit_transform(comb.values), columns= lb.classes_)
print (df)
