AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

SymPy is a Python computer algebra system (CAS) for symbolic mathematics, enabling manipulation and simplification of mathematical expressions, equations, and calculus operations.

Installation is straightforward with low friction; the package has a single runtime dependency (mpmath) and is actively maintained with recent releases.

SymPy is licensed under the permissive BSD license, allowing both commercial and private use with minimal restrictions, making it suitable for most projects without licensing concerns.

Usage

pip install sympy

from sympy import Symbol, cos
x = Symbol('x')
e = 1/cos(x)
print(e.series(x, 0, 10))

Requires Python 3.9 or later; mpmath is automatically installed as a runtime dependency.

Verdict: SymPy is a mature, actively maintained symbolic mathematics library with no known vulnerabilities, permissive licensing, and low installation friction. It is well-suited for scientific computing, mathematical research, and educational use across Python 3.9–3.13.

Needs verification

Performance characteristics and computational limits for large or complex symbolic expressions.
Compatibility and integration patterns with other scientific Python libraries.
Memory footprint and scalability for production workloads involving many simultaneous symbolic operations.
