Webx, y, z, t = symbols('x y z t') SymPy symbols are just objects and when you do operations on two sympy objects the result is a sympy object. When you combine a sympy and python object, the result is also a sympy object. But we need to be careful when doing fractions. For instance doing x + 1/3 will first compute 1/3 in python (giving 0 or 0.333 ... WebJun 30, 2024 · This is an issue that came from SO. It highlights significant issues with parsing/handling an expression that is created in an evaluate (False) environment.
