Pandas index column title or name

How do I get the index column name in python pandas? Here’s an example dataframe:

             Column 1
Index Title          
Apples              1
Oranges             2
Puppies             3
Ducks               4  

What I’m trying to do is get/set the dataframe index title. Here is what i tried:

import pandas as pd
data = {'Column 1'     : [1., 2., 3., 4.],
        'Index Title'  : ["Apples", "Oranges", "Puppies", "Ducks"]}
df = pd.DataFrame(data)
df.index = df["Index Title"]
del df["Index Title"]
print df

Anyone know how to do this?
