PyRival is a Python library of algorithms, data structures, and templates for competitive programming. It includes battle-tested snippets for number theory, graphs, geometry, and strings, plus tools like stress testers and interactive runners.

Use cases

• prepare a python template for codeforces contests
• find a fast fenwick tree implementation in python
• implement miller-rabin primality testing for a contest problem
• stress test a brute force solution against an optimized one
• copy snippets for fft, ntt, or chinese remainder theorem
• speed up competitive programming solutions for pypy

When to choose

• you compete in online judges like Codeforces or AtCoder using Python or PyPy
• you want a curated, tested collection of contest-ready algorithm snippets
• you need a single-file template that works across Python and PyPy versions

When to avoid

• you need a production-grade general-purpose algorithms library with stable APIs
• you want pip-installable dependencies for application development rather than copy-paste snippets
• you work in a language other than Python
