How to simultaneoulsy expand and shrink the dataframe as per some conditions?
Question:
i have a df as follows:
df = pd.DataFrame.from_dict({'Type': {0: 'A1', 1: 'A2', 2: 'A2', 3: 'A2', 4: 'A2', 5: 'A3', 6: 'A3', 7: 'A3', 8: 'A3', 9: 'A3', 10: 'A3', 11: 'A3', 12: 'A3', 13: 'A3', 14: 'A3', 15: 'A3', 16: 'A3',

I wanted to expand and shrink columns simulataneously such that the output look as follws:
Type POS FN VC ID DN FC SCZ BPAD PC
A1 C1 F1 MI S1 D1 1 0 0 0
A2 C2 F2 MI S2 D2 0 1 0 0
C3 F3 IN S3|S4 D3|D4 1 1 0 0
C4 F4 MI S5 D5 0 1 0 0
A3 C5 F5 MI S6 D6 1 0 0 0
F6 MI S8|S9|S10|S11 D8|D9|D10|D11 3 0 0 1
F7 MI S12|S13 D11|D12 2 0 0 0
C6 F5 LOF S6 D6 1 0 0 0
C7 F1 MI S1 D1 1 0 0 0
F5 MI S7 D7 1 0 0 0
F8 MI S15 D15 0 0 1 0
C8 F1 MI S1 D1 1 0 0 0
F8 MI S14 D14 0 0 1 0
I tried the following code to shrink and expand the data
df1 = df.groupby(['Type', 'FN']).agg(lambda x: '|'.join(x.unique()))[['POS', 'VC', 'ID', 'DN']]
df2 = pd.get_dummies(df.set_index(['Type', 'FN'])['Group']).sum(level=[0, 1])
pd.concat([df1, df2], axis=1)
But in the output POS also got splitted, but I wanted to expand that
Answers:
I think you need aggregate per 3 columns:
df1 = df.groupby(['Type','POS', 'FN'])[['VC','ID','DN']].agg(lambda x: '|'.join(x.unique()))
df2 = pd.get_dummies(df.set_index(['Type','POS', 'FN'])['Group']).sum(level=[0, 1, 2])
df = pd.concat([df1, df2], axis=1)
print (df.head(20))

I wanted to expand and shrink columns simulataneously such that the output look as follws:
Type POS FN VC ID DN FC SCZ BPAD PC
A1 C1 F1 MI S1 D1 1 0 0 0
A2 C2 F2 MI S2 D2 0 1 0 0
C3 F3 IN S3|S4 D3|D4 1 1 0 0
C4 F4 MI S5 D5 0 1 0 0
A3 C5 F5 MI S6 D6 1 0 0 0
F6 MI S8|S9|S10|S11 D8|D9|D10|D11 3 0 0 1
F7 MI S12|S13 D11|D12 2 0 0 0
C6 F5 LOF S6 D6 1 0 0 0
C7 F1 MI S1 D1 1 0 0 0
F5 MI S7 D7 1 0 0 0
F8 MI S15 D15 0 0 1 0
C8 F1 MI S1 D1 1 0 0 0
F8 MI S14 D14 0 0 1 0
I tried the following code to shrink and expand the data
df1 = df.groupby(['Type', 'FN']).agg(lambda x: '|'.join(x.unique()))[['POS', 'VC', 'ID', 'DN']]
df2 = pd.get_dummies(df.set_index(['Type', 'FN'])['Group']).sum(level=[0, 1])
pd.concat([df1, df2], axis=1)
But in the output POS also got splitted, but I wanted to expand that
I think you need aggregate per 3 columns:
df1 = df.groupby(['Type','POS', 'FN'])[['VC','ID','DN']].agg(lambda x: '|'.join(x.unique()))
df2 = pd.get_dummies(df.set_index(['Type','POS', 'FN'])['Group']).sum(level=[0, 1, 2])
df = pd.concat([df1, df2], axis=1)
print (df.head(20))
