Pandas DataFrame.keys() method returns the columns of the DataFrame as an Index object.

Examples

Consider the following DataFrame:

df = pd.DataFrame({"A":[3,4], "B":[5,6]})
df
A B
0 3 5
1 4 6

To get the columns of df:

df.keys()
Index(['A', 'B'], dtype='object')

The returned value is of type Index, and so you can access the actual column labels using [] syntax like so:

df.keys()[0]
'A'
