how to get a elliptic lseries() at 1,2,3,4,5........
E = EllipticCurve('39a');
E.lseries()
Complex L-series of the Elliptic Curve defined by y^2 + xy = x^3 + x^2 - 4x - 5 over Rational Field
how to get lseries value at 1,2,3...by Euler product in sage?
I find there no sagecode about lseries value at http://www.lmfdb.org/EllipticCurve/Q/...
