I have written the following:
T=[0]*2
S=[]
l=2
for i in range(l):
T[0]=i
T[1]=i+1
print T
S.append(T)
Now S becomes [[1, 2], [1, 2]] instead of [[0,1],[1,2]].
In my situation, length l of S is not fixed. Is there any
method to solve this problem?

Thank you.
magma found parametrization too, so the problem is in sage/singular.
(probably you mean genus zero, not one).

Maple agrees with magma here and says that the genus is one. Moreover, it

I wanted to get lattice of transitive subgroups. Few questions rising from
that:
I can say
G=[s for s in SymmetricGroup(5).conjugacy_classes_subgroups() if
s.is_transitive()];
[[G[n].is_subgroup(s) for s in G] for n in range(len(G))];
but then I got quite unreadable list. In general, Sage

return mpmath.zeta(x)+mpmath.zeta(x,derivative=1)
r=mpmath.findroot(F,[0.1+mpmath.j],solver=muller)

This probably occurred because a *compiled* component of Sage
Hmm. My backtrace showed:
/home/mcneil/sagedev/sage-5.4.beta0/local/lib/libcsage.so(print_backtrace+0x3b)[0xb6bd7c49]
/home/mcneil/sagedev/sage-5.4.beta0/local/lib/libcsage.so(sigdie+0x17)[0xb6bd7c89]
i get the same exception on standalone mpmath, don't know if it uses
gmp.

From source or just a binary?
