I\'m not sure where I am astray but I cannot seem to reset the index on a dataframe.

When I run test.head(), I get the output below:

I would add to in code veritas's answer:

If you already have an index column specified, then you can save the del, of course. In my hypothetical example:

    df_total_sales_customers = pd.DataFrame({'Sales': total_sales_customers['Sales'],
                              'Customers': total_sales_customers['Customers']}, index = total_sales_customers.index)

    df_total_sales_customers = df_total_sales_customers.reset_index()
