A method to discretize numerical features by Python

This is as follows:

data = np.random.randn(20)
 
factor = pd.cut(data,4)
 
pd.get_dummies(factor)
 
0	0	0	0	1
1	1	0	0	0
2	0	0	0	1
3	0	0	1	0
4	1	0	0	0
5	0	1	0	0
6	0	1	0	0
7	0	1	0	0
8	0	0	1	0
9	0	1	0	0
10	0	0	0	1
11	0	1	0	0
12	0	1	0	0
13	0	0	1	0
14	0	0	1	0
15	0	1	0	0
16	0	1	0	0
17	1	0	0	0
18	0	0	1	0
19	0	0	0	1

Where the 4 in the parameter indicates that, divided into 4 segments.
