![The provided skeleton file (CryptoPriceChecker.py) contains a class called PriceChecker, which will contain
most of your code. At the bottom of the file is the Main Code Section (not indented and therefore not part of
the PriceChecker class), which is used to create an object based on this PriceChecker class, and then allows
the user to invoke the object's methods via a menu.
The PriceChecker class has a single list[] variable - called levelsList- and getter and setter properties to
manipulate its values. This levelsList attribute must be used to store the price levels (float values) that the
user entered. The app must allow the user to enter as many values in the list as desired.
The provided PriceChecker class contains partially completed methods to sort, display and manipulate the
values in levelsList.
Instructions
| 1. Complete all code sections that are marked with ellipsis ...). Base your code on the functionality of the
particular method and the comments added above the ellipsis. The methods in question are displayList(),
addLevel(), removeLevel() and removeAllLevels().

Transcribed Image Text:For this project, we are going to create an app that keeps an eye on the Bitcoin price -via the BitMex
exchange.
The app will contact the exchange every two seconds to obtain the latest Bitcoin price. It must compare the
latest Bitcoin price with the previously obtained price (obtained two seconds before) and display it in a
specific colour, depending on whether the price moved up, down or stayed unchanged.
The app must also sound an alarm if the price moves above or below any of the userentered price levels.
During each week, we will do a predetermined section of the required work-called a Sprint in Agile
Development (a specific project management style used extensively in many IT development projects).
In this first sprint, we will enable the user to add and remove price levels to the levelslist.
