Python | Pandas MultiIndex.from_product()

Python is a great language for doing data analysis, primarily because of the fantastic ecosystem of data-centric python packages. Pandas is one of those packages and makes importing and analyzing data much easier. Pandas MultiIndex.from_product() function make a MultiIndex from the cartesian product of multiple iterables.

Syntax: MultiIndex.from_product(iterables, sortorder=None, names=None) Parameters : iterables : Each iterable has unique labels for each level of the index. sortorder : Level of sortedness (must be lexicographically sorted by that level). names : Names for the levels in the index. Returns: index : MultiIndex

Example #1: Use MultiIndex.from_product() function to construct a MultiIndex from the cartesian product of multiple iterables. Python3

# importing pandas as pd
import pandas as pd

# Create the first iterable
Price =[20, 35, 60, 85]

# Create the second iterable
Name =['Vanilla', 'Strawberry']

# Print the first iterable
print(Price)

# Print the second iterable
print("\n", Name)

Output : Now let's create the MultiIndex using the above two iterables. Python3

# Creating the MultiIndex
midx = pd.MultiIndex.from_product([Name, Price],
                       names =['Name', 'Price'])

# Print the MultiIndex
print(midx)

Output : As we can see in the output, the function has created a MultiIndex object using the cartesian product of these two iterables.   Example #2: Use MultiIndex.from_product() function to construct a MultiIndex from the cartesian product of multiple iterables. Python3

# importing pandas as pd
import pandas as pd

# Create the first iterable
Snake =['Viper', 'Cobra']

# Create the second iterable
Variety =['Brown', 'Yellow', 'Black']

# Print the first iterable
print(Snake)

# Print the second iterable
print("\n", Variety)

Output : Now let's create the MultiIndex using the above two iterables. Python3

# Creating the MultiIndex
midx = pd.MultiIndex.from_product([Snake, Variety], 
                       names =['Snake', 'Variety'])

# Print the MultiIndex
print(midx)

Output : The function has created a MultiIndex using the two iterables.
