46. Problem To Create A Python Class Example

In this Python oops program, we will create a Python class example. Python class called ShoppingCart with attributes items and total_cost.

The ShoppingCart class has a constructor method __init__ that initializes two instance variables: self.items as an empty list to store the items in the cart, and self.total_cost as 0 to track the total cost of the items.
The class also has three methods:
The add_item method takes item and cost as parameters and appends the item to the self.items list and adds the cost to the self.total_cost.
The remove_item method takes item and cost as parameters and removes the item from the self.items list if it exists and subtracts the cost from the self.total_cost.
The calculate_total_cost method returns the self.total_cost, representing the total cost of the items in the cart.
The code creates an object cart of the ShoppingCart class by calling its constructor without any arguments.
The add_item method is called three times on the cart object to add three items: “Shirt” with a cost of 250, “Pants” with a cost of 500, and “Shoes” with a cost of 1000.
The remove_item method is called on the cart object to remove the “Shirt” item with a cost of 250.
The calculate_total_cost method is called on the cart object to calculate the total cost of the items in the cart, and the result is assigned to the total_cost variable.
Finally, the contents of the cart are printed using cart.items, and the total cost is printed using total_cost.
Thus, we have created Python class example.
