Pandas DataFrame을 참가자별 DataFrame으로 효율적으로 분할하려면 어떻게 해야 합니까?

import pandas as pd
import numpy as np

# Create sample data with a 'Names' column
data = pd.DataFrame({'Names': ['Joe', 'John', 'Jasper', 'Jez'] * 4,
                     'Ob1': np.random.rand(16),
                     'Ob2': np.random.rand(16)})

# Create a unique list of names
UniqueNames = data.Names.unique()

# Create a dictionary to store the split dataframes
DataFrameDict = {elem: pd.DataFrame() for elem in UniqueNames}

# Iterate through UniqueNames and slice the original data
for key in DataFrameDict.keys():
    DataFrameDict[key] = data[data.Names == key]

# Access a specific dataframe using its name
specific_dataframe = DataFrameDict['Joe']
