Pandas Dataframe of boolean to classification Serie

Question

I have a Pandas DataFrame like that:

	A	B	C	D	E	F
0	False	False	False	False	False	True
1	False	True	False	False	False	False
2	False	True	False	False	False	False
3	False	True	False	False	False	False
4	True	False	False	False	False	False

And I want to transform it into a Serie like:

	Classes
0	F
1	B
2	B
3	B
4	A

Is someone knows the way to do that ? :D

Answer 1

You could try with .dot:

output = df.dot(df.columns).rename("Classes")

>>> output
0    F
1    B
2    B
3    B
4    A
Name: Classes, dtype: object
