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. https://www.sympy.org/ Signed-off-by: Julien Olivain <ju.o@free.fr> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com>
