it seems that the variable you're using is a dictionary.

You have to access to the values of the key : avgmotion by simply putting the information in variable, let's assume your dictionary's variable is name_of_dict.

   avgmotion = name_of_dict["avgmotion"]

After that you can check the shape and size of your array and try to extract whatever data you want.
