Python Pandas | How to create a MultiIndex with names of each of the index levels?

Consider the below examples –

Example 1:

# Import the pandas package
import pandas as pd

# Create arrays
arrays = [[101, 102, 103], ['Shivang', 'Radib', 'Monika']]

# Create a Multiindex using  from_arrays() 
mi = pd.MultiIndex.from_arrays(arrays, names=('ids', 'student'))

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

# Get the names of levels in Multiindex
print("The names of levels in Multi-index...\n",mi.names)

Output:

The MultiIndex...
 MultiIndex([(101, 'Shivang'),
            (102,   'Radib'),
            (103,  'Monika')],
           names=['ids', 'student'])
The names of levels in Multi-index...
 ['ids', 'student']

Example 2:

# 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 names of levels in MultiIndex
print("The names of levels in Multi-index...\n",mi.names)

Output:

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