我有以下数据帧:
amount catcode cid cycle date di feccandid type
0 1000 E1600 N00029285 2014 2014-05-15 D H8TX22107 24K
1 5000 G4600 N00026722 2014 2013-10-22 D H4TX28046 24K
2 4 C2100 N00030676 2014 2014-03-26 D H0MO07113 24Z
我想为列中的值创建虚拟变量type.大约15岁.我试过这个:
pd.get_dummies(df['type'])
它返回:
24A 24C 24E 24F 24K 24N 24P 24R 24Z
