To get a specific group after calling groupby(~), use the get_group(~) method, which returns a DataFrame.
Example
Consider the following DataFrame:
df = pd.DataFrame({"price":[200,300,700,900], "brand":["apple", "google", "apple", "google"], "device":["phone","phone","computer","phone"]})df
price brand device0 200 apple phone1 300 google phone2 700 apple computer3 900 google phone
To get the group "apple" as a DataFrame:
df.groupby("brand").get_group("apple")
price brand device0 200 apple phone2 700 apple computer
