What, precisely, is the function of the delete operator?
What precisely does it mean when you use the delete operator?
Please help me write the following function (see the photos for context of the problem): follow_trail(filename, treasure_map, start_row, start_col): Takes as inputs a string corresponding to a filename, a list of lists corresponding to a treasure map, and two non-negative integers representing a row and column index. Follows the trail in the given treasure map, starting at the given row and column index. Following the trail means to look at each character of the trail and perform the appropriate operation for that character: '>', '<', 'v', ' ∧': Continues following the trail by moving to the character to the right, left, below or above the current trail character, respectively. '.': Creates a new map file, with 'new_' prepended to the current map filename, and stores the same treasure map but with an X at the current position. Then, returns a tuple of three elements: the first being -1, and the latter two being the current row and column index. '*': Returns a tuple of three…

Exercise: Check Monster Character Exists Description In this series of exercises, you will create functions to create, modify and examine dictionaries that represent characters in an animated film, and the cast members who voice the characters. The keys of the dictionary will be character names. The values in the dictionary will be voice actor names. For this exercise, you will create a function that checks if a character is already in the dictionary. Files monsterfunctions.py : set of functions to work with monster cast dictionaries. Function Name has_character Parameters monsters: a dictionary character: a string, the name of a character Action Checks if character is a key in monsters. Return Value True if character is a key in monsters, otherwise False. Examples monsters = create_monster_cast() monsters = add_cast_member(monsters, "Mike", "William Crystal") has_character(monsters, "Mike") -> True has_character(monsters, "Sully") -> False

PERBE The start time of the trip should be considered zero. In other words, assuming we start the trip at 12:00am, this function should return the time it takes for the trip to finish, including all the waiting times before, and between the flights. If there is no path available, return -1.0 >>> calculate_trip_time("AA1", 2.0 >>> calculate_trip_time("AA1", >>> calculate_trip_time("AA1", >>> calculate_trip_time("AA1", 0.0 >>> calculate_trip_time("AA4", 14.0 >>> calculate_trip_time("AA1", 7.5 >>> calculate_trip_time("AA1", 2.0 *** "AA2", ["AA1", "AA2"], TEST_FLIGHTS_DIR_FOUR_CITIES) "AA7", ["AA7"] "AA1"], TEST_FLIGHTS_DIR_FOUR_CITIES) "AA7", ["AA1",…
