Create a sub columns in the dataframe using a another dataframe

Question

I am new to the python and pandas. Here, I have a following dataframe .

did           features   offset   word   JAPE_feature  manual_feature 
0             200          


        

Answer 1

Use get_dummies with DataFrame.reindex:

feat = [100,200,2200,2600,156,162,4600,100]
df = df.join(pd.get_dummies(df.pop('features')).reindex(feat, axis=1, fill_value=0))
print (df)
   id  100  200  2200  2600  156  162  4600  100
0   0    0    1     0     0    0    0     0    0
1   1    0    1     0     0    0    0     0    0
2   2    0    1     0     0    0    0     0    0
3   4    1    0     0     0    0    0     0    1
4   5    1    0     0     0    0    0     0    1
5   7    0    0     1     0    0    0     0    0
6   8    0    0     0     1    0    0     0    0
7   9    0    0     0     1    0    0     0    0
8  10    0    0     0     0    0    0     1    0

If need MultiIndex only pass mux to reindex, but also convert id column to index:

feat = [100,200,2200,2600,156,162,4600,100]
mux = pd.MultiIndex.from_product([['features'],feat])

df = pd.get_dummies(df.set_index('id')['features']).reindex(mux, axis=1, fill_value=0)
print (df)
   features                                   
       100  200  2200 2600 156  162  4600 100 
id                                            
0         0    0    0    0    0    0    0    0
1         0    0    0    0    0    0    0    0
2         0    0    0    0    0    0    0    0
4         0    0    0    0    0    0    0    0
5         0    0    0    0    0    0    0    0
7         0    0    0    0    0    0    0    0
8         0    0    0    0    0    0    0    0
9         0    0    0    0    0    0    0    0
10        0    0    0    0    0    0    0    0

EDIT:

cols = ['features', 'JAPE_feature', 'manual_feature']

df = pd.get_dummies(df, columns=cols)
df.columns = df.columns.str.rsplit('_',1, expand=True)
print (df)

8    1              0   0    0    0    1  

If want avoid missing values in MultIndex in columns for columns with no MultiIndex:

cols = ['features', 'JAPE_feature', 'manual_feature']
df = df.set_index(df.columns.difference(cols).tolist())

df = pd.get_dummies(df, columns=cols)
df.columns = df.columns.str.rsplit('_',1, expand=True)
print (df)
                features                    JAPE_feature                     \

did offset word

EDIT:

If want compare some column from list by manual_feature column use DataFrame.eq with converting to integers:

cols = ['JAPE_feature', 'features']
df1 = df[cols].eq(df['manual_feature'], axis=0).astype(int)
print (df1)
   JAPE_feature  features
0             1         1
1             1         1
2             1         0
3             1         0
4             0         1
5             1         1
6             0         1
7             1         1
8             1         1
