Instruction

Okay! When you analyze data, you often want to check the names of the columns. Each DataFrame has a field named columns that contains the names of all its columns. Take a look:

hospital.columns

This line of code returns the names of the hospital DataFrame's columns in the following format:

Index(['Hospital Name', 'City', 'State', 'Phone Number', 'Hospital overall rating'], dtype='object')

The Index object works very similarly to a Python list. You can index it or slice it in the same way as you would a Python list:

hospital.columns[3]
hospital.columns[1:5]

Exercise

Display the names of columns from the eu_states DataFrame.
