There are lots of ways to do that in Python--depends on what kind of
a list you have. For example, if I have a string list of elliptic
curve labels, and want a list of curves...
sage: s = "37a|15a|389a"
sage: [EllipticCurve(ss) for ss in s.split('|')]
[Elliptic Curve defined by y^2 + y = x^3 - x over Rational Field,
Elliptic Curve defined by y^2 + x*y + y = x^3 + x^2 - 10*x - 10
over Rational Field,
Elliptic Curve defined by y^2 + y = x^3 + x^2 - 2*x over Rational
Field]
You can do the same or integers, real numbers, symbolic equations
(use SR(ss)), with any separator, etc. Python has a lot of
documentation on string processing.
