Solve the following python programming problem given the following code:
@ defun 
def ellipfun(ctx, kind, u = None, m = None, q = None, k = None, tau = None) : 
    try : 
        S = jacobi_spec [kind] 
except KeyError : 
        raise ValueError ("First argument must be a two-character string containing 's', 'c', 'd' or 'n', e.g.: 'sn'") 
if (u is None) : 
        def f(* args, **kwargs) : 
            return ctx.ellipfun (kind, * args, ** kwargs) 
f.__name__ = kind 
        return f 
prec = ctx.prec 
    try : 
        ctx.prec += 10 
        u = ctx.convert (u) 
        q = ctx.qfrom (m = m, q = q, k = k, tau = tau) 
        if (S is None) : 
            v = (c.one + ((0 * q) * u)) 
else : 
            if (q == ctx.zero) : 
                if (S [4] == '1') : 
                    v = ctx.one 
else : 
                    v = getattr (ctx, S [4]) (u) 
v += ((0 * q) * u) 
else : 
                if (q == ctx.one) : 
                    if (S [5] == '1') : 
                        v = ctx.one 
else : 
                        v = getattr (ctx, S [5]) (u) 
v += ((0 * q) * u) 
else : 
                    t = (u / (ctx.jtheta (3, 0, q) ** 2)) 
                    v = ctx.one 
                    for a in S [0] : 
                        v *= ctx.jtheta (a, 0, q) 
for b in S [1] : 
                        v /= ctx.jtheta (b, 0, q) 
for c in S [2] : 
                        v *= ctx.jtheta (c, t, q) 
for d in S [3] : 
                        v /= ctx.jtheta (d, t, q) 
finally : 
        ctx.prec = prec 
return (+ v) 

    
    

    Fix the buggy line: v = (c.one + ((0 * q) * u))

#Here is Python code to fix the buggy line: v = (c.

v = (ctx.one + ((0 * q) * u))
