# 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 + x*y = x^3 + x^2
- 4*x - 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/...
