Pandas - Groupby and create new DataFrame?

2024/11/18 19:37:11

This is my situation -

In[1]: data
Out[1]: Item                    Type
0  Orange           Edible, Fruit
1  Banana           Edible, Fruit
2  Tomato       Edible, Vegetable
3  Laptop  Non Edible, ElectronicIn[2]: type(data)
Out[2]: pandas.core.frame.DataFrame

What I want to do is create a data frame of only Fruits, so I need to groupby such a way that Fruit exists in Type.

I've tried doing this:

grouped = data.groupby(lambda x: "Fruit" in x, axis=1)

I don't know if that's the way of doing it, I'm having a little tough time understanding groupby. How do I get a new DataFrame of only Fruits?

Answer

You could use

data[data['Type'].str.contains('Fruit')]

import pandas as pddata = pd.DataFrame({'Item':['Orange', 'Banana', 'Tomato', 'Laptop'],'Type':['Edible, Fruit', 'Edible, Fruit', 'Edible, Vegetable', 'Non Edible, Electronic']})
print(data[data['Type'].str.contains('Fruit')])

yields

     Item           Type
0  Orange  Edible, Fruit
1  Banana  Edible, Fruit
