There is the .columns attribute given by the Pandas library that will give you the current columns of a DataFrame.

You might end up needing to change them.

To do so, you will need to assign a list of new column names to the DataFrame.columns as so:

# we assign the new columns to the dataframe.columns attribute
df.columns = ["col1","col2","col3"]

Be careful to match the correct number of columns that your DataFrame currently have or you will run into an error.

In order to rename the index column you will assign a new value to the index.name attribute as so:

df.index.name = "my_new_index_column_name"

Here you are ! You know how to rename both columns and index columns of a DataFrame.
