說我有從示例數(shù)據(jù)集在這里：import pandas as pdraw_data = {'regiment': ['Nighthawks', 'Nighthawks', 'Nighthawks', 'Nighthawks', 'Dragoons', 'Dragoons', 'Dragoons', 'Dragoons', 'Scouts', 'Scouts', 'Scouts', 'Scouts'], 'company': ['1st', '1st', '2nd', '2nd', '1st', '1st', '2nd', '2nd','1st', '1st', '2nd', '2nd'], 'name': ['Miller', 'Jacobson', 'Ali', 'Milner', 'Cooze', 'Jacon', 'Ryaner', 'Sone', 'Sloan', 'Piger', 'Riani', 'Ali'], 'preTestScore': [4, 24, 31, 2, 3, 4, 24, 31, 2, 3, 2, 3], 'postTestScore': [25, 94, 57, 62, 70, 25, 94, 57, 62, 70, 62, 70]}df = pd.DataFrame(raw_data, columns = ['regiment', 'company', 'name', 'preTestScore', 'postTestScore'])df我想做一個(gè)regimentvs的箱線圖preTestScore。為此，我需要找出這兩個(gè)變量的相對(duì)分布。所以，我regiment按preTestScore以下方式分組：df1 = df['regiment'].groupby(df['preTestScore']).count()df1preTestScore2 33 34 224 231 2Name: regiment, dtype: int64
如何將對(duì)熊貓數(shù)據(jù)框進(jìn)行分組操作后獲得的數(shù)據(jù)結(jié)構(gòu)轉(zhuǎn)換為數(shù)據(jù)框？
