I wrote the below code

    (eta, _) = _get_coeff_exp(g1.argument, x)
    (omega, _) = _get_coeff_exp(g2.argument, x)
    def neg(l):
        return [(- x) for x in l]
    a1 = (neg(g1.bm) + list(g2.an))
    a2 = (list(g2.aother) + neg(g1.bother))
    b1 = (neg(g1.an) + list(g2.bm))
    b2 = (list(g2.bother) + neg(g1.aother))
    return (meijerg(a1, a2, b1, b2, (omega / eta)) / eta)
