I expect something like this,
df (original):
index feature1(target column) feature2 feature3 feature4
0 0 1 2 3 4
1 1 1 2 3 4
2 2 1 2 3 4
3 3 1 2 3 4
df1:
feature1(target column) feature2 feature3
0 1 2 3
1 1 2 3
2 1 2 3
3 1 2 3
df2:
feature1(target column) feature2 feature4
0 1 2 4
1 1 2 4
2 1 2 4
3 1 2 4
df3:
feature1(target column) feature3 feature4
0 1 3 4
1 1 3 4
2 1 3 4
3 1 3 4
df4:
feature1(target column) feature2 feature4
0 1 2 4
1 1 2 4
2 1 2 4
3 1 2 4
Try this and see if it helps:
import itertools
import pandas as pd
df = pd.DataFrame({
'col1': [1, 2, 3, 4, 5],
'col2': [1, 2, 3, 4, 5],
'col3': [1, 2, 3, 4, 5],
'col4': [1, 2, 3, 4, 5]
})
target_col = ['col4']
iterable = list(set(df.columns.tolist()).difference(target_col))
r = len(iterable) - 1
cmbs = itertools.combinations(iterable, r)
# print(df[iterable])
for item in cmbs:
features = df[list(item)]
print(item)
