About

-----

**python-oeis** is a Python library for exploring and retrieving integer sequences from the `Online Encyclopedia of Integer Sequences (OEIS) `_. Use it to search for sequences by keywords, fetch classic sequences like the Fibonacci numbers (A000045), primes (A000040), or your favorite obscure sequence, and access OEIS metadata programmatically.

Requirements

------------

- Python 3.8 or higher

- `requests `_

Installation

------------

Install the latest stable release from PyPI:

.. code-block:: sh

    # Unix / macOS

    python3 -m pip install "python-oeis"

    # Windows

    py -m pip install "python-oeis"

To install the development version from GitHub:

.. code-block:: sh

    git clone https://github.com/Ombucha/python-oeis

    cd python-oeis

    pip install .

Usage Example

-------------

Query the OEIS for sequences, just like searching for A-numbers or keywords on the OEIS website:

.. code-block:: python

    import oeis

    # Search for sequences related to 'prime numbers'

    results = oeis.search('prime numbers')

    for seq in results[:3]:

        print(seq.id, seq.name, seq.data[:10])

    # Fetch the Fibonacci sequence (A000045)

    fib = oeis.Sequence('A000045')

    print(fib.name)

    print(fib.data[:10])  # First 10 Fibonacci numbers
