Write a function named csv_to_kvs that takes a string as a parameter representing the name of a CSV file with 4 columns in the format "<string>,<float>,<float>,<float>" and returns a new dictionary mapping strings to decimal numbers. The returned dictionary will have a key-value pair for each row in the file. The key for each pair is the data in the initial column of the CSV file and values are the data from the column at index 2. (in python )

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…

Hand trace Figure 5-20 on page 262 and produce a trace table based on this ordered input: Lot number 1 has a property value of 1000.Lot number 2 has a property value of 2000.Lot number 3 has a property value of 500.Lot 0 will end the program. No need to illustrate the Display output this time; I only want you to trace the variables. Take a snapshot of the completed trace table.

Please use javascript to write the function. write the code for the edit() function. This function prompts the user for a unique code. If the entered unique code is matched with the random-generated unique code for the respective user, store the user index and reason index to the local storage with their relevant key. Then redirect the user to the edit page. Otherwise, if the unique code cannot match with the user’s random-generated unique code, alert the user by mentioning that incorrect unique code.
