from sklearn.compose import ColumnTransformer


data = {"fruits": ['apple','orange', 'banana', 'orange', 'apple'],
        "price": [10,20,5,20,10],
        'color': ['red', 'orange', 'yellow', 'orange', 'red']}
df = pd.DataFrame(data)


transformers = [
    ('Ohe', OneHotEncoder(), [0,2]),
    ('scaler', StandardScaler(), [1])
]
ct = ColumnTransformer(transformers = transformers)
