P2PU Python course: Objects

#Tasks
#1. Two objects: Car and Gas Station
#2. List several attributes for each object
#3.  List at least one method that the object employs
#4. Create Python pseudocode for each object, don't forget the __init__() function.
#5. Post your pseudo code to this task discussion.
# Extra Credit: Have one of the objects return information that is utilized by the other object.
