convert Symengine I to python 1j

I want to convert Symengine complex number I to python 1j so that I can use these numbers in normal python. Currently, I have a code but it runs using sympy which makes it slower. Any alternative solution for this or speed up this code?. Here is the code I have:

import sympy
from time import time
from symengine import *
def sym2num(x):
    return complex(sympy.sympify(x))

Here is the reference from which I took the code

Thank you

Solution

  • There's no built-in way to do this in SymEngine yet (PRs are welcome).

    Here's a workaround that is reasonably fast.

    def sym2num(x):
    return float(x.real_part()) + float(x.imaginary_part())*1j
