Remove index name in pandas

Question

I have a dataframe like this one:

In [10]: df
Out[10]: 
         Column 1
foo              
Apples          1
Oranges         2
Puppies         3
Ducks           4

How to remove index name foo from that dataframe? The desired output is like this:

In [10]: df
Out[10]: 
         Column 1             
Apples          1
Oranges         2
Puppies         3
Ducks           4

Answer 1

Use del df.index.name

In [16]: df
Out[16]:
         Column 1
foo
Apples          1
Oranges         2
Puppies         3
Ducks           4

In [17]: del df.index.name

In [18]: df
Out[18]:
         Column 1
Apples          1
Oranges         2
Puppies         3
Ducks           4

Answer 2

Alternatively you can just assign None to the index.name attribute:

In [125]:

df.index.name = None
df
Out[125]:
         Column 1

Apples          1
Oranges         2
Puppies         3
Ducks           4

Answer 3

From version 0.18.0 you can use rename_axis:

print df
         Column 1
foo              
Apples          1
Oranges         2
Puppies         3
Ducks           4

print df.index.name
foo


print df.rename_axis(None)
         Column 1
Apples          1
Oranges         2
Puppies         3
Ducks           4

print df.rename_axis(None).index.name
None

# To modify the DataFrame itself:
df.rename_axis(None, inplace=True)
print df.index.name
None

Answer 4

You can delete index name by using the following line of code:

del df.index.name
