WebWe can abbreviate the creation of multiple symbolic variables using the symbols function. For example, to create the symbolic variables x, y and z, we can use. In [6]: import sympy x, y, z = sympy.symbols('x,y,z') x + 2*y + 3*z - x. Out [6]: 2 y + 3 z. Once we have completed our term manipulation, we sometimes like to insert numbers for variables. WebSymPy uses mpmath in the background, which makes it possible to perform computations using arbitrary-precision arithmetic. That way, some special constants, like , , (Infinity), are treated as symbols and can be evaluated with arbitrary precision: >>> sym. pi ** 2
