How to convert a single column Pandas DataFrame into Series

Question

I have the following data frame:

import pandas as pd
d = {\'gene\' : [\'foo\',\'bar\'],\'score\' : [4., 3.,]}
df = pd.DataFrame(d)
df.set_index(\'gene\',inpl         


        

Answer 1

Swapping the indices would solve the problem easily:

In [64]: type(df.iloc[0:,])
Out[64]: pandas.core.frame.DataFrame

In [65]: df.iloc[[:,0] // Swaped the indices
Out[65]:
        score
gene
foo       4
bar       3
