How to Compute the Cartesian Product of Two Lists in Python

Generates all ordered pairs from two lists using itertools.product and prints each combination.

itertools cartesian-product combinations
Python
from itertools import product

# Two small input lists
list_a = [1, 2, 3]
list_b = ["x", "y"]

# Compute the Cartesian product
result = list(product(list_a, list_b))

# Display the result
print("Cartesian product of", list_a, "and", list_b, "is:")
for pair in result:
    print(pair)
