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 fennel0 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_fennel0 1 0 1 0 1 0 0 1 1 0 1 0 0 0 0 ....

In this post, we will learn about pandasâ€™ data structures/objects. Pandas provide two type of data structures:- ### Pandas Series Pandas Series is a one dimensional indexed data, which can hold datatypes like integer, string, boolean, float...

In the programming world, Data types play an important role. Each Variable is stored in different data types and responsible for various functions. Python had two different objects, and They are mutable and immutable objects.
