1.0) head Function Define and implement this function in data_utils.py. Purpose: Produce a new column-based (e.g. dict[str, list[str]]) table with only the first n (a parameter) rows of data for each column. Why: Visualizing a table with hundreds, thousands, or millions of rows in it is overwhelming. You frequently want to just see the first few rows of a table to get a sense you are on che correct path. • Function name: head Parameters: 1. dict[str, list[str]]-a column-based table of data that will not be mutated 2. int - The number of "rows" to include in the resulting list • Return type: dict[str, list[str]] mplementation strategy: 1. Establish an empty dictionary that will serve as the returned dictionary this function is building up. 2. Loop through each of the columns in the first row of the table given as a parameter. 1. Inside of the loop, establish an empty list to store each of the first N values in the column. 2. Loop through the first N items of the table's column, 1. Appending each item to the previously list established in step 2.1. 3. Assign the produced list of column values to the dictionary established in step 1. 2 Doturn tho dietio

5 partition_list (head) This is a little like split_list() from the Short problem, except that, instead of splitting the list into two by cutting it into the middle, you will now build two lists to return, using alternate values. The first value in the input list should be returned at the head of the first new list; the second value should be the head of the second list. Keep on alternating from there, putting one new value on the first list, and one on the second. (But remember that the length of the input list might be odd.) Example Suppose you have the following input list: 10 - 13 -> -1 -> 1000 - 0 It should return the following two lists: 10 1 0 13 -> 1000

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",…

Game of Hunt in C++ language   Create the 'Game of Hunt'.  The computer ‘hides’ the treasure at a random location in a 10x10 matrix. The user guesses the location by entering a row and column values. The game ends when the user locates the treasure or the treasure value is less than or equal to zero. Guesses in the wrong location will provide clues such as a compass direction or number of squares horizontally or vertically to the treasure. Using the random number generator, display one of the following in the board where the player made their guess: U#  Treasure is up ‘#’ on the vertical axis (where # represents an integer number). D# Treasure is down ‘#’ on the vertical axis (where # represents an integer number) || Treasure is in this row, not up or down from the guess location. -> Treasure is to the right. <- Treasure is to the left. -- Treasure is in the same column, not left or right. +$ Adds $50 to treasure and no $50 turn loss. -$ Subtracts…

Write function week() that takes no arguments. It will repeatedly ask the user to enter anabbreviation for a day of the week (Mo, Tu, We, Th, Fr, Sa, or Su) and then print thecorresponding day. Use a dictionary to implement this result.>>> week() Enter day abbreviation: TuTuesdayEnter day abbreviation: SuSundayEnter day abbreviation: SaSaturdayEnter day abbreviation

Overview This is a review assignment where you will use multiple tools you have picked up so far throughout the course. If you're confused about how to do something make sure you look back at earlier assignments. In this program you will start by declaring an empty dictionary named population_dict. Then you will use a while-loop to prompt a user for a series of cities and their populations, storing the input in population_dict). After this you will prompt the user to decide what is the maximum population for a city to be considers a small down. Finally, you will open a file called populationdata.txt where you will write the results. Expected Output Example of standard out (the console): What is next city? (enter q to quit) Long Beach What is the population of Long Beach? 362000 What is next city? (enter q to quit) Los Angeles What is the population of Los Angeles? 382000000 What is next city? (enter q to quit) San Diego What is the population of San Diego? 136000000 What is next city?…
