Python: Create two dummy columns from one column

Question

I have a one column Pandas dataframe:

'asdf'

0
1
1
1
0
...
1

How do I turn it into:

1    0
0    1
0    1
0    1
1    0

such that the first column is the "0" column and the second column is the "1" column and both are dummy variables?

Answer 1

You can use get_dummies , for example

import numpy as np
import pandas as pd

one = pd.DataFrame({'asdf':np.random.randint(0,2,10)})
two = pd.get_dummies(one.loc[:,'asdf'])
