create_numbers_dictionary(numbers) which takes a list of integers as a Define a function called parameter and creates a dictionary by looping through each element in the list. The dictionary is to have three keys: 0, 1, and 2. A key of 0 represents numbers from 0-9, a key of 1 represents numbers from 10 - 19 and a key of 2 represents numbers from 20 - 29. The value is the frequency count of the range of numbers in the parameter list. Note: you can assume that all numbers are always >= 0 and < 30.

Write a function and test that creates a dictionary containing the Canadian provinces and territories as keys and their capitals as values. (Use the Internet to get a list of the provinces and their capitals.) The __main__ guard portion of the program should then randomly quiz the user by displaying the name of a state and asking the user to enter that state’s capital. The program should keep a count of the number of correct and incorrect responses. （Use python and pytest）
Write a function called list_to_dict(lst) that takes a 2-D list of sales records of this form.[["customer1", "bread", 5], ["customer2", "bread", 4.5], ["customer1", "egg", 6.75]]Your function will store the sales information in a dictionary, where each {key:value} pair of the dictionary stores {a unique customer: [ a list of all products purchased by this customer, total cost of these products]}, and returns the dictionary. Sample run,sales = [ ["customer1", "bread", 5], ["customer2", "bread", 4.5], ["customer1", "egg", 6.75],["customer2", "milk", 4.35], ["customer3", "egg", 3.6], ["customer4", "bread", 4.5],["customer1", "milk", 4.35], ["customer2", "egg", 3.6], ["customer4", "milk", 4.35] ]>>> record = list_to_dict(sales)>>> display(record)customer1 : [['bread', 'egg', 'milk'], 16.1]customer2 : [['bread', 'milk', 'egg'], 12.45]customer3 : [['egg'], 3.6]customer4 : [['bread', 'milk'], 8.85]
Complete the below function that takes a file name and a list as arguments andreads the text within the corresponding file, then creates a dictionary whosekeys are the characters of the provided list, and the values are the counts ofthese characters within the text. If a character in the list is not included inthe text, "0" should be written in the dictionary as the value of thischaracter. The function returns the created dictionary as a result. If the filedoes not exist, then the function returns an empty dictionary.""" write it into the code below.def text2dict(filename, characters):return # Remove this line to answer this question

Program in C. Help please! Write some code in the main() function to accomplish the following tasks:  Read the supplied data from datafile city.dat  Build an adjacency matrix based on the city.dat datafile  Create an alphabetized list of cities for selection by the user  Display the cities from which to select using a number that your program assigns from the alphabetized list of cities that is dynamically created from your city.dat file. Example: Please select an origin city Enter a number associated with one of the cities below: Amsterdam --- 1 Belgrade --- 2 Bern --- 3 Genoa --- 4 Hamburg --- 5 Lisbon --- 6 Madrid --- 7 Having written code to extract data from the keyboard (stdin) in Lab 3, reuse that code to prompt the user to enter a number, verifying that the number entered is an integer and is between 0 and the maximum number of available cities in the list. You should ignore any invalid entries such as float values, letters, punctuation, whitespace, etc.  Display the above…
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…
The following are your requirements: make_dict(n) Write a function called make_dict(n), where n is an integer parameter. With a given number n, make a new dictionary in your function where the keys in the dictionary are in the range from 1 to n, and value for each key is the square of the key for that entry. Your function should return this dictionary, not print it. main() Call make_dict(n), where the user is asked to specify a number to pass into make_dict(n), and then prints the returned dictionary object.

1. Write a function invert_dict to reverse a dictionary, for example: >>> eng2sp = {'one': 'uno', 'two': 'dos', 'three': 'tres'} >>> sp2eng = invert_dict(eng2sp) >>> sp2eng {'uno':'one', 'dos':'two', 'tres':'three'} 2. Write a function print_dict to print all the key-values in a dictionary, for example: >>> d2 {'a': 'one', 'b': 'two', 'c': 'Three'} >>> print_dict(d2) a:one b:two c:Three
(PYTHON) a) get_total_cases() takes the a 2D-list (similar to database) and an integer x from this set {0, 1, 2} as input parameters. Here, 0 represents Case_Reported_Date, 1 represents Age_Group and 2 represents Client_Gender (these are the fields on the header row, the integer value represents the index of each of these fields on that row). This function computes the total number of reported cases for each instance of x in the text file, and it stores this information in a dictionary in this form {an_instance_of_x : total_case}. Finally, it returns the dictionary and the total number of all reported cases saved in this dictionary. (Suppose we want to know the total number of cases reported on each date, so use x = 0.) >>> result, total_cases = get_total_cases(database, 0) >>> display_dict(result) 2021-05-19: 8 2021-05-20: 2 2021-05-21: 1 2021-05-22: 1 >>> print(total_cases) 12
Write a function named build_dict() that will take a string and an index as parameters. The function will remove all the characters of the positions which are multiples of the given index (Except the index itself) and print those removed characters inside the function as a STRING.Lastly, the function will RETURN a dictionary that will have the removed characters as keys and their ASCII values as values.Sample Input 1:Bangladesh3Function call 1:build_dict("Bangladesh", 3)Sample Output 1:Removed: dh{'d': 100, 'h': 104}Explanation 1:Here, the multiples of 3 are 6 and 9 (excluding 3 itself); so the function will remove ‘d’, ‘h’, print those removed characters INSIDE the function.Then the function returns the dictionary that has ‘d’, ‘h’ as keys and their ASCII values(100,104) as values.Sample Input 2:Programming2Function call 2:build_dict("Programming", 2)Sample Output 2:Removed: rmig{'r': 114, 'm': 109, 'i': 105, 'g': 103}
Please answer it in Python Write a function init_line that takes as an argument a pickaxe list corresponding to the list of cards after distribution of cards to players. This function removes the first 4 cards from the deck (it is assumed that there are suffisamment) and uses them to start the 4 lines of the game board. It therefore returns a dictionary according to the format defini in part 3 (key = line number, associated value = list of cards in the line). The first card of the pickaxe will go to the first line, and so on. The function also has an edge effet: it modifies pickaxe. For example: Card =[74, 72, 59, 82, 44, 77, 17, 11, 62, 97, 83, 69, 100, 22, 4, 51, 55, 50, 103, 52, 13, 25, 38, 37, 29, 104, 47, 23, 39, 80, 49, 98, 8, 78, 26, 46, 86, 18, 93, 31, 27, 34, 85, 84, 76, 87, 65, 35, 81, 79, 101, 66, 20, 91, 73, 16, 102, 42, 40, 70, 90, 7, 6, 64, 14, 67, 43, 12, 58, 1, 63, 2, 75, 32, 48, 96, 3, 15, 99, 68, 53, 61, 56, 92, 36, 28, 19, 5, 24, 45, 57, 94, 21, 54, 88, 33, 10, 71,…
