- 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…arrow_forwardPYTHON QUESTION This assignment requires you to create a dictionary by reading the text file created for the Chapter 6 assignment. The dictionary should have player names for the keys. The value for each key must be a two-element list holding the player's goals and assists, respectively. See page 472! Start with an empty dictionary. Then, use a loop to cycle through the text file and add key-value pairs to the dictionary. Close the text file and process the dictionary to print the stats and determine the top scorer as before. In fact, much of the code used in program6_2.py can be copied and used for this program. Printing the stats for each player is the most challenging part of this program. To master this, refer to the examples in the zip file that can be downloaded from the "Dictionary values can be lists" link in the "Learn Here" part of this module. NOTE: you do not need to submit the text file. Submit just this program. The required output should be the same well-formatted table…arrow_forwardHow do I do this using pythonarrow_forward
