Please answer it in Python Write a function distribute_cartes that has two mandatory arguments card and players and an optional argument nb_card whose default value is 10. The pick argument corresponds to the complete list of cards in the game, already shuffled. The players list corresponds to the list of player names. This function allows the action of distributing nb_card cards from the pickaxe to each of the players. She builds a djeux dictionary whose keys are the names of the players and associating with each name the list of cards corresponding to her game. We will make sure to sort the game of each player in ascending order using the spell function. The distribute_card function returns the dictionary and modifies its pickaxe argument by edge effet (cards dealt to players must be removed from the pickaxe). It is assumed here that the pickaxe contains sufficiently cards for all players. For example card = [74, 72, 59, 82, 44, 77, 17, 11, 62, 97, 83, 69, 100, 22, 4, 51, 55, 50,…
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,…
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）

The names are further categorized under "Actors" and "Actresses".You are given the following dictionary where you have a nested dictionary containing a tuple.my_dictionary = {'American': {'Actors': ('Tom Cruise', 'Leonardo DiCaprio'), 'Actresses': ('Scarlett Johansson', 'Angelina Jolie')}, 'Korean': {'Actors': ('Lee in-ho', 'Song Joong-ki','Choi Jin-hyuk')}, 'German': {'Actors': ('David Kross', 'Michael Fassbender'), 'Actresses':('Diana Kruger')}}Write a python function that will take this dictionary as an argument in a function call which will convert this dictionary into the following tuple and return it.[Hint: You might need to…
Write a function called login that accepts 3 parameters: userName:str, password: str, and data: dictionary. The data parameter is a dictionary containing userName keys and associated passwords for values. Your function is the check if the username and password passed by parameter are a matching key:value pair in the data dictionary. in python If the username is not a valid key in data it should return the string "The user name was not found" If the password is not correct for a username that is found in the data dictionary it should return the string "The password was incorrect" If the username is associated with a correct password it should return the string "Login successful" You can create an empty dictionary with dictionary() [ ] ( ) { } This data structure stores a collection of objects in an unordered manner where each object must be unique dictionary set tuple list

Use Python for this question. Also, could you please comment/explain what each line of code represents in this question. Write a function piggyBank that accepts a sequence of "coins" and returns counts of the coins and the total value of the bank. the coins will be given by a list of single characters, each one of 'Q','D','N',P' , representing quarter, dime, nickel, penny the function returns a tuple with two items: a dictionary with counts of each denomination. They should always be listed in the order 'Q','D','N',P' the total value in whole cents of the amount in the bank Output for this question is shown in the attached image
