The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

    Thank you for your interest. There are some interesting examples in the SWE-bench-lite benchmark which are resolved by AutoCodeRover:

    - From sympy: AutoCodeRover's patch for it:

    - Another one from scikit-learn: AutoCodeRover's patch ( modified a few lines below (compared to the developer patch) and wrote a different comment.

    There are more examples in the results directory (

    That's interesting. You should consider yourself lucky to have met Wolfram employees, as they are obviously vastly outnumbered by users of Mathematica.

    I have not met any developers for either of these products but I know that SymPy has a huge list of contributors for a project of its size. See:

    You may not be hearing about SymPy users because SymPy is not a monolithic product. It is a library. If you know mathematicians big into using Python, they are probably aware of SymPy as it is the main attraction when it comes to symbolic computation in Python.

  • Has anyone solved the prime number problem on SPOJ yet using pure python?

    Look at sympy.isprime for a carefully-optimized pure-Python solution (though if gmpy2 is installed, which it usually is, it will use that instead after trying the easiest cases)

What are some alternatives?

When comparing NumPy and SymPy you can also consider the following projects:

Pandas - Flexible and powerful data analysis / manipulation library for Python, providing labeled data structures similar to R data.frame objects, statistical functions, and much more

SciPy - SciPy library main repository

blaze - NumPy and Pandas interface to Big Data

Numba - NumPy aware dynamic Python compiler using LLVM

NetworkX - Network Analysis in Python

Nim - Nim is a statically typed compiled systems programming language. It combines successful concepts from mature languages like Python, Ada and Modula. Its design focuses on efficiency, expressiveness, and elegance (in that order of priority).

ti84-forth - A Forth implementation for the TI-84+ calculator.

manim - Animation engine for explanatory math videos

Ndless - The TI-Nspire calculator extension for native applications
