Spelling out my name using multiple turtles in turtlesim

edit

I'm entirely new to ROS and I was playing around with turtlesim and decided to create a basic program to draw my name using multiple turtles. I was wondering if there is a way to create a node to create multiple turtles using script instead of having to type [rosservice call /spawn x y theta " " ]

So let us say that I have to create three turtles at different points, and the name and sequence of the turtles matter as well. (Ex - turtle at 1,1 must be turtle 2. turtle at 5,2 must be turtle 3). How can I create a node, or a file that may serve this purpose. I would appreciate any help. Thank you!
