[Tutor] role playing game - help needed

[Al Stern]

Ok.  I think I am starting to get it but still not sure how to separate the
value from the key.  Once I have this...

attributes = {"strength": 0, "health": 0, "wisdom": 0, "dexterity": 0}
MAX_POINTS = 30

How do I set the variable for available_points?

available_points = MAX_POINTS - (not sure what goes here)

I am pretty sure I will change the values by something like this...

attributes["strength"] = input("\nHow many points do you want to assign to
strength?: ")

Please let me know if this isn't advisable.  It seems to work on the
surface.
