Concept explainers

Passing Array as Argument

An array is a data structure that holds only fixed-size data and its contents are arranged in contiguous memory slots. The primary purpose of using an array is to store data items of the identical type together. An array can stockpile any one of the following types of data: int, float, char and so forth. The elements are stored from index 0, and the difference between the two indexes of the array is termed as an offset. The array has a fixed size. Once the size is defined during array declaration, it cannot be changed later.

Question

Please answer this with PYTHON LANGUAGE. thank you The developers of a free online game named Sugar Smash have asked you to develop a class named SugarSmashPlayer that holds data about a single player. The class contains the following fields: idNumber - the player’s ID number (of type int), name - the player's screen name (of type String), scores - an array of integers that stores the highest score achieved in each of 10 game levels Include get and set methods for each field. The get method for scores should require the game level to retrieve the score for. The set method for scores should require two parameters—one that represents the score achieved and one that represents the game level to be retrieved or assigned. Display an error message if the user attempts to assign or retrieve a score from a level that is out of range for the array of scores. Additionally, no level except the first one should be set unless the user has earned at least 100 points at each previous level. If a user…
