REST APIs with Flask and Python - Solution to Coding Exercise: Classes and Objects

The video tutorial covers a coding exercise involving the implementation of three methods in a class: the init method, the add item method, and the stock price method. The init method initializes object properties, the add item method appends items to a list, and the stock price method calculates the total price using list comprehension. The tutorial emphasizes understanding assumptions in code and improving readability with concise Python techniques.

What is the first step recommended before starting the coding exercise?

• Discuss with a peer

• Write pseudocode

• Read a Python book

• Review the previous exercise

What does the init method initialize in the class?

• Only the name property

• Neither name nor items properties

• Only the items property

• Both name and items properties

What arguments does the add_item method take?

• Only price

• Name, price, and quantity

• Name and price

• Only self

What is the purpose of the add_item method?

• To append a dictionary with name and price to items

• To sort items by price

• To update item prices

• To remove items from the list

How does the stock_price method calculate the total price?

• By multiplying all prices

• By summing up all item prices

• By subtracting discounts

• By averaging the prices

What is a more concise way to calculate the total price using Python?

• Using a for loop

• Using a while loop

• Using list comprehension

• Using a dictionary

What is the benefit of using list comprehension in the stock_price method?

• It requires more memory

• It is more concise and readable

• It is less readable

• It makes the code longer
