Is SymPy a Python library?
SymPy is a Python library for symbolic mathematics. It aims to become a full-featured computer algebra system (CAS) while keeping the code as simple as possible in order to be comprehensible and easily extensible. SymPy is written entirely in Python. SymPy is… Free: Licensed under BSD, SymPy is free both as in speech and as in beer.
What is SymPy documentation?
Welcome to SymPy’s documentation! # A PDF version of these docs is also available. SymPy is a Python library for symbolic mathematics. If you are new to SymPy, start with the introductory tutorial.
What is the purpose of this SymPy tutorial?
This tutorial aims to give an introduction to SymPy for someone who has not used the library before. Many features of SymPy will be introduced in this tutorial, but they will not be exhaustive. In fact, virtually every functionality shown in this tutorial will have more options or capabilities than what will be shown.
Is SymPy free?
Free: Licensed under BSD, SymPy is free both as in speech and as in beer. Python-based: SymPy is written entirely in Python and uses Python for its language. Lightweight: SymPy only depends on mpmath, a pure Python library for arbitrary floating point arithmetic, making it easy to use.
