SUPyF2 Objects/Classes-Exericse - 06. Inventory

Problem:
Create a class Inventory. The __init__ method should accept only the capacity of the inventory.
The capacity should be a private attribute (__capacity). You can read more about private attributes here.
Each inventory should also have an attribute called items, where all the items will be stored.
The class should also have 3 methods:
• add_item(item) - adds the item in the inventory if there is space for it. Otherwise, returns
"not enough room in the inventory"
• get_capacity() - returns the value of __capacity
• __repr__() - returns "Items: {items}. Capacity left: {left_capacity}". The items should be separated by ", "

Examples:
Test Code:
inventory = Inventory(2)
inventory.add_item("potion")
inventory.add_item("sword")
inventory.add_item("bottle")
print(inventory.get_capacity())
print(inventory)

Output:
not enough room in the inventory
2
Items: potion, sword.
Capacity left: 0
