Consider the below example –

Python code to get the names of levels in MultiIndex

# Import the pandas package
import pandas as pd

# Create arrays
cities = [
        ['New Delhi', 'Mumbai', 'Banglore', 'Kolkata'],
        ['New York', 'Los Angeles', 'Chicago', 'Houston']
    ]

# Create a Multiindex using from_arrays() 
mi = pd.MultiIndex.from_arrays(cities, names=('india_cities', 'usa_cities'))

# display the Multiindex
print("The MultiIndex...\n",mi)

# Get the levels in MultiIndex
print("The levels in MultiIndex...\n",mi.levels)

# Get the names of levels in MultiIndex
print("The names of levels in MultiIndex...\n",mi.names)

Output:

The MultiIndex...
 MultiIndex([('New Delhi',    'New York'),
            (   'Mumbai', 'Los Angeles'),
            ( 'Banglore',     'Chicago'),
            (  'Kolkata',     'Houston')],
           names=['india_cities', 'usa_cities'])
The levels in MultiIndex...
 [['Banglore', 'Kolkata', 'Mumbai', 'New Delhi'], ['Chicago', 'Houston', 'Los Angeles', 'New York']]
The names of levels in MultiIndex...
 ['india_cities', 'usa_cities']
