Mar 8, 2023 · The permutations() function in Python, part of the itertools module, generates all possible ordered arrangements of a given iterable (like a list, string, or tuple). Unlike combinations, where order doesn't matter, permutations consider the order of elements.

itertools.permutations generates where its elements are treated as unique based on their position, not on their value. So basically I want to avoid duplicates like this: >>> list(itertools.permutations([1, 1, 1])) [(1, 1, 1), (1, 1, 1), (1, 1, 1), (1, 1, 1), (1, 1, 1), (1, 1, 1)]

Feb 26, 2025 · This blog post will explore the fundamental concepts of permutations in Python, how to use them, common practices, and best practices to help you efficiently implement permutation-related operations in your projects.

Jul 3, 2021 · Explores the difference between combinations and permutations, and why you don't need to write your own Python code for them because the built-in itertools module already exists. Includes working code examples.
