Thepurpose of this assignment is to gain experience in Python dictionary structure, create basicPython functions and import a module.Design solution: The template file contains a list of clothes item sold, each item in the listcontains the item id, name of the item and the prices. The program will generate an items_dictwhere each key is the item id of the cloth and the values will be a list of item name and priceinformation. A customer will be presented with a main menu with 4 different options: displayall items, add an item to cart, checkout and exit the program. A customer can buy an item byentering the ID of the item. This program implements a dictionary called cart, where each key isthe item id and the values are the list of name, price and quantity that user chooses topurchase. The program keeps repeating by displaying the main menu to…185e def find(self, key): 186e 187 188 Efficiency: 189 Finds and returns a copy of value in the set that matches key.

This is now the function that frees (destroys) a dictionary: void dict_destroy (dict_t* dict); This operates just as dict_clear, but in addition should free the memory that was allocated during dict_create. After a call to this function, if any other library function receives the pointer dict, the behavior is undefined (most likely, it will crash). This simple function returns the current size of the dictionary: size_t dict_size (const dict_t* dict);
