WHAT TO SUBMIT? This homework assignment asks you to submit only one flle whose name must be playlist. py. This file should contain at least seven functions whose desails are given above. Remember that the headers of these functions must be def add_song (playlist, title, year, singer): def, remove_song(playlist, title) it det like_song(playlist, title)t def unlike_song (play1ist, title): def display_all_songs (playlist)i def display_al1_liked_songs(playlist): det show_song(play1ist, title)t Your file may contain other auxilary functions, which might be called frem the aforementioned four functions. However, it SHOULD NOT contain a function whose name is main (). Additionally, thid file SHOULD NOT have amy statements written outside a function definition. We will test your functions writing cur own main function, similar to the one given below, and calling this main function to start the program. - "IMPORTANT: You MUST use the given function headers as they are. We will use these headers to call your functions and test them. You are NOT allowed to modify thege function headers. If you modify them, you will get no points from the corresponding part since we cannot call your functions properly, and thus, we cannot test and grade them. Additionally, If your file contains a function called main () or if it has a statement outside any function definition, you may lose a considerable number of points. Note that although you will not submit a main function, you should, of course, write a main SHOW A SONG This function displays all information about a song whose title is specified as a parameter. The output should be in the following format, If the song with the specified title does not exist in the playlist, the function displays a warning mestage.
