Problem in chapter 3

whenever i run the listener python script i get only an out put saying follower_model_name model_to_be_followed_name help in this regard pls been trying to figure out why this is happening but no clue.

so turns out i also have to give the names of the models for the python script to work haha finally figured it out : )


Its asking you to execute the python script with extra arguments, in this case:

python turtle1 turtle2

Have a look at the code and you will see in the main method that two arguments are asked for ;).
