How to fix the problem in pandas.get_dummies

I'm preprocessing my dataset with pd.get_dummies, but the result is not what I need.

I'm preprocessing my dataset with pd.get_dummies, but the result is not what I need.

Is it correct to use pd.get_dummies()? Or any approaches I can try?

import pandas as pd
rawdataset=[['apple','banana','carrot','daikon','egg'],
           ['apple','banana'],
           ['apple','banana','carrot'],
           ['daikon','egg','fennel'],
           ['apple','banana','daikon']]
dataset=pd.DataFrame(data=rawdataset)
print(pd.get_dummies(dataset))

I expect it looks like this:

   apple banana carrot daikon egg fennel 

0 1 1 1 1 1 0 1 1 1 0 0 0 0 ........

not like this:

   0_apple  0_daikon  1_banana  1_egg  2_carrot  2_daikon  2_fennel  

0 1 0 1 0 1 0 0 1 1 0 1 0 0 0 0 ....
