Solve the following python programming problem given the following code:
def standardize_infinite(ctx, f, intervals) : 
    if (not f) : 
        return f 
(dim, [a, b]) = intervals [(- 1)] 
    if (a == ctx.ninf) : 
        if (b == ctx.inf) : 
            def g(* args) : 
                args = list (args) 
                k = args [dim] 
                if k : 
                    s = f (* args) 
                    args [dim] = (- k) 
                    s += f (* args) 
                    return s 
else : 
                    return f (* args) 
else : 
            def g(* args) : 
                args = list (args) 
                args [dim] = (b - args [dim]) 
                return f (* args) 
else : 
        def g(* args) : 
            args = list (args) 
            args [dim] += a 
            return f (* args) 
return standardize_infinite (ctx, g, intervals [: (- 1)])
