blue component. For example, if the color is (0,255,64), the proper return value would be: #0OFF40 But you don't need to know how hexdecimal works! (Until you take 252.) If you are using f-strings, you can add a "format specifier" to show Python how you want the variable be printed out. To format an integer foo as exactly two uppercase hex characters, use format string f"foo={foo : 02X]" . get_rgb(self) Finally, the function get_rgb() returns the red, green, blue components as a tuple. . set_standard_color (self, name) This class does not let you change the colors individually. Instead, you can set the color to one of four standard colors. The new color must be given as a string. Perform a case-insensitive check; if it is red, yellow, white, or black, set the r,g, b components of the object to the proper values. (You can find the proper RGB values for each color at the link above.) . remove_red (self) Set the red component of the current color to zero. Leave the green andUsage Example obj = Band ("Elvis Presley") obj. set_drummer ("Chad Smith") obj . play_music() 6 class Color The class Color represents an RGB (https://en. wikipedia. org/wiki/RGB_ color_model) color. It stores the red, green, and blue components of the color as integers; each one is in the range [0,255] (inclusive). It has the methods defined below. All of the data fields must be private fields. Define this class inside classes-prob2. py . . __init__(self, r,g,b) Constructor. This class should accept values that are too large or too small; but should bound them; that is, any value less than 0 should be set to 0, and any number larger than 255 should be set to 255. (Since you're doing exactly the same thing three times, you are required to use a function here, to contain the common code.) . __str__(self) Instead of using getters for the individual colors, this class has three meth- ods that allow you to view the color in different ways. The __str__() method, (which, of course, is the method that Python will call if you call str(object) ) returns a string that has red, green, and blue components (in that order); the complete string looks like this: rgb (10, 20,30) (Don't include any whitespace, including any newline character.) Did you realize that Python's f-strings (which we've used for formatted output) work to build a string for any purpose - not just for printing? . html_hex_color(self) html_hex_color () returns the same information as __str__() , but en- coded the way that colors are often specified on web pages (https :/ / www . w3schools. com/colors/colors_hex. asp). These start with a hash character (#) and then have 6 hexdecimal characters (0 through 9, A through F). The first two represent the red component of the color, the next two represent the green component, and the last two represent theThe four exits, however, should be public fields; they should simply have the names n, s, w, e . Each exit is either a reference to another Room object, or else None (meaning that the wall has no exit in that direction). All exits must be symmetric. That is, if you have an East exit that points to another Room, then that Room must have a West exit which comes back to the current room. Next, you will write one non-trivial method: collapse_room (), which rep- resents a cave-in. In this method, which is called on a certain Room, you must set all of the exits of that room to None. In addition, in each adjacent Room, you must set the exit coming back to None as well - so that it's impossible to reach this room anymore, from anywhere else. Define this class inside classes_prob3. py 7.1 Room: Required Methods . __init__(self, ????) Your class must include a constructor. However, my testcases will never create any Room objects directly (only through calling build_grid()), so you have total freedom about what you want the parameter(s) to be. . get_name (self ) set_name (self , name) Getter and setter for the room name. The name must always be a string. . collapse_room (self) Breaks all exits to and from this room. All of the exits leaving this room are set to None; in addition, in each adjacent room, the link to this room is set to None. 7.2 Factory Function: build_grid() In addition to the class, your file classes_prob3. py must also define a function (not a method of any class) named build_grid(wid, hei). This will build a two-dimensional grid of Room objects, where the width (that is, the West-East size) and the height (that is, the North-South size) are as given. You may assume (without checking) that the height and width are both 2 1. You must allocate all of the necessary Room objects, and link them together with their exits. Rooms on the edge of the grid will have one exit which is None (those in the corner will of course have two Nones). You must return the Room object representing the Southwest corner. Do not return an array or other data structure; you must return a reference to a single object. While I don't care what names you give to the various rooms, you must give the rooms different names. You can come up with any scheme that you want (given them grid coordinate names), randomly select names from a pool,5 class Band Band represents a musical group. It can contain one singer, one drummer, and any number of guitar players. When the object is created, it will only contain a singer; use getters and setters to update the various band members. (It has the members defined below.) All of the data fields must be private fields. Define this class inside classes_prob1 . py . . _ _init__(self, singer) Constructor. It should store the singer it is passed, set the drummer to None, and record that the band does not (yet) have any guitar players. . get_singer (self) set_singer (self, new_singer) get_drummer (self) set_drummer (self, new_drummer) These are the getters and setters for the singer and the drummer. . add_guitar_player (self, new_guitar_player) fire_all_guitar_players(self) The Band can have any number of guitar players: from 0 to as many as you like. The class begins with 0, when it is created; to add a player, you can call add_guitar_player () . You cannot change players once they are added, or remove them one at a time; the only way to get rid of the guitar players is to fire all of them, all at once.I get_guita1'_players(ae1f) When you call get_guitar_players(), the Band class must return a list of guitar players and the players must be listed in the order that they were added to the band. However, the list must not be a reference to some internal list that you are using to store the guitar players you must duplicate that information into a new list. 'Why would you do this? Because if you didn't. the caller can modify the list without asking you which changes what the Band thinks is its list of guitar players. Should you do this in the Real \"World?I Sometimes! In some programs+ isolating the two code components is critical so you would duplicate the array, for safety. But in other programs, performance might be more important - so you might return the array (and take the risk) because it's faster (and easier]. I p1ay_nuaic(aelf) The band plays some music, based on the members of the band. We represent this by printing various lines of output. First, the singer sings. The class knows of two special singers, Frank Sinatra and Kurt Cobain. All other singers sound exactly the same. If the singer is ' 'Frank Sinatra' ' (httpa :Hm.youtube . confvatch?w QSTMB-IUQE), then print the following: Do be do be do If the singer is ' 'Kurt Cobain' ' (https:quoutubemomfsatow FklUAoZEKxY). then print the following: bugle needle zones Otherwise, print the following: La la la Next, the drummer plays the drums. If the drummer is None, then print nothing; however. if the drummer is not None, then print the following: Bang bang bang! Finally. the guitars play. For each guitar player in the hand, print the following Strum! 7.2 Factory Function: builtLgridO In addition to the class1 your le c1uses.prob3.py must also dene a. function [not a method of any claim) named build_grid{vid,hei). This will build a two-dinlensional grid of Room objects, where the width (that isI the WestEast size) and the height (that is, the NorthSouth size) are as given. You ma}r assume {without checking) that the height and width are both 2 1. You must allocate all of the necessary Roan objects, and link them together with their exits. Rooms on the edge of the grid will have one exit which is None [those in the corner will of course have two Hones}. You must return the Room object representing the Southwest oorner. Do not return an array or other data structurei you must return a. reference to a single object. While I don"t care what names you give to the various rooms1 you must give the rooms different names. You can come up with any 5611131119 that you want (given them grid coordinate names], randomly select names from a pool, ate. Homer, you must (EDIIIEhDW) guarantee that (3) every name is a string blue components unchanged. Usage Example obj = Color (0, 500, 0) # will get bounded to (0, 255,0) x = str(obj) # returns "rgb (0, 255,0)" obj. set_standard_color ("WHITE") 7 class Room The class Room represents a room in some underground maze; it might be used, perhaps as part of a MUD (https://en. wikipedia. org/wiki/MUD). Each room has four exits, which often (not always) lead to other rooms. The ex- its are n, s, w, e - representing the four points of the compass. In a real Room object that was part of a game, there would be many different properties (like a description, a list of objects on the floor, etc.). But for our little class, you will only need to support two types of fields: a name (which must be a string) and the four exits. The name must be a private field; thus, you must store it in a variable whose name starts with a single underscore. You must provide a getter and setter for the name
