            stack.append(i)
        elif i in closeList:
            pos = closeList.index(i)
            if ((len(stack) > 0) and (openList[pos] == stack[len(stack)-1])):
                stack.pop()
            else:
                return "Unbalanced"
    if len(stack) == 0:
        return "Balanced"
print balance("{[()](){}}")
