Define a function named create_usernames_dictionary (usernames_list) which takes a list of usernames as a parameter and creates a dictionary. The keys consist of integers and the values are lists of unique usernames where the last digit of each username is equal to the key value. The lists of unique words must be in sorted alphabetical order. Note: A username contains 3 or 4 letters followed by 3 digits. You can assume the list is not empty. For example: Test Result = a_list ['dsmi001', 'dsmi023', 'pwong002', 'kng126', 'mgra734', 'bcar735', 'dng134¹] [] a_dict = create_usernames_dictionary (a_list) 1 ['dsmi001'] for key in sorted (a_dict): 2 ['pwong002¹] print(key, a_dict [key]) 3 ['dsmi023'] 4 ['dng134', 'mgra734'] 5 ['bcar735¹] 6 ['kng126¹] 7 [] 8 [] 9 [] Answer: (penalty regime: 0, 0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50 %) Reset answer 1-def create_usernames_dictionary (usernames_list): 2 result dict = (0:1, 1:1, 2:1, 3:1, 4:1, 5:1, 6:1, 7:11, 8:11, 9:11}

Data structures concatenate_dict(dict_list:list)->dict This function will be given a single parameter known as the Dictionary List. Your job is to combine all the dictionaries found in the dictionary list into a single dictionary and return it. There are two rules for adding values to the dictionary: 1. You must add key-value pairs to the dictionary in the same order they are found in the Dictionary List. 2. If the key already exists, it cannot be overwritten. In other words, if two or more dictionaries have the same key, the key to be added cannot be overwritten by the subsequent dictionaries. Example: Dictionary List: [{'Z': 6, 'k': 10, 'w': 3, 'I': 8, 'Y': 5}, {'Y': 1, 'Z': 4}, {'X': 2, 'L': 5}] Expected: {'Z': 6, 'k': 10, 'w': 3, 'I': 8, 'Y': 5, 'X': 2, 'L': 5} Dictionary List: [{'z': 0}, {'z': 7}] Expected: {'z': 0} Dictionary List: [{'b': 7}, {'b': 10, 'A': 8, 'Z': 2, 'V': 1}] Expected: {'b': 7, 'A': 8, 'Z': 2, 'V': 1}
Data structures dict_from_string(dict_str:str)->dict This function will be given a single parameter, a string representing a dictionary. Your job is to convert the string into an actual dictionary and return the dictionary. Make sure all key-value pairs in the string exist in the newly created dictionary. The string will contain only numbers or single letters as key values pairs. Make sure all letters are kept as strings and all numbers are converted to integers in the newly created dictionary. Example: String Input: '{9: 'V', 'G': 0, 'M': 9, 'u': 3, 2: 'o', 8: 'u', 'q': 9, 'D': 1}' Expected: {9: 'V', 'G': 0, 'M': 9, 'u': 3, 2: 'o', 8: 'u', 'q': 9, 'D': 1} String Input: '{10: 'D', 1: 'Z', 5: 'a'}' Expected: {10: 'D', 1: 'Z', 5: 'a'} String Input: '{'M': 2, 'V': 0, 3: 'x', 6: 'J', 5: 'J', 7: 'T', 8: 'P', 4: 'q', 1: 'h'}' Expected: {'M': 2, 'V': 0, 3: 'x', 6: 'J', 5: 'J', 7: 'T', 8: 'P', 4: 'q', 1: 'h'} String Input: '{3: 'D', 10: 'T', 7: 'm', 'u': 9, 't': 5, 6: 'Z', 'H': 10, 'B':…
Data structures dict_contains_keys(items:set, example_dict:dict)->bool This function will have two parameters. The first is a set of numbers known as Number Set. The second is a dictionary known as Dictionary. Dictionary will have keys as integers and values as letters. The functions should return true if at least one of the numbers in the Number set is a key in Dictionary. It should return false otherwise. Example: Items: {8, 10, 5} Example: {9: 'F', 10: 'X'} Expected: True Items: {8, 9, 5, 1} Example: {6: 'i', 5: 'Y', 1: 'N', 0: 'E'} Expected: True Items: {9, 10, 4} Example: {5: 'i', 3: 'o', 1: 'N'} Expected: False
Python Programming Assignment: Create a dictionary that takes a basketball team's information (that includes team's name and points) as parameter, creates a teams_dict and returns it. Also, create a parameter for write_file parameter that opens current results text file in write mode and writes the dictionary information to file as per format and closes the file.
Exercise: Check Monster Character Exists Description In this series of exercises, you will create functionsto create, modify and examine dictionaries thatrepresent characters in an animated film, and thecast members who voice the characters. Thekeys of the dictionary will be character names.The values in the dictionary will be voice actornames. For this exercise, you will create a function thatchecks if a character is already in the dictionary. Files • monsterfunctions.py : set of functions to work with monster cast dictionaries. Function Name has_character Parameters • monsters: a dictionary • character: a string, the name of a character Action Checks if character is a key in monsters. Return Value True if character is a key in monsters, otherwise False. Examples monsters = create_monster_cast()monsters = add_cast_member(monsters, "Mike", "William Crystal")has_character(monsters, "Mike") -> Truehas_character(monsters, "Sully") -> False
Exercise: empty_dictionary Description In this exercise, your function will receive no parameters. It will create an empty dictionary and return it. Function Name empty_dictionary Parameters None Return Value An empty dictionary. Examples empty_dictionary() > 0)

Data structures return_growing_num_list(max:int) -> list This function will be given a single number, it should return a list of strings of numbers. Each string in the list will only contain a single number repeated an arbitrary amount of times. The number each string will contain will be equal to the current string's index+1. The number in the string should be repeated the same number of times as the string's index+1. Each number in the string should be separated by a space. This list should stop when its size equals the max number specified. Example: max = 3 output = ['1', '2 2', '3 3 3'] max = 4 output = ['1', '2 2', '3 3 3', '4 4 4 4']
Python coding language Create a static dictionary with a number of users and with the following values: First name Last name Email address Password Ask the user for: 5. Email address 6. Password Loop (for()) through the dictionary and if (if()) the user is found print the following: 7. Hello, first name last name you have successfully logged in 8. Notify the user if the password and email address are wrong 9. Additional challenge: if you want the program to keep asking for a username and password when the combination is wrong, you will need a while() loop. 10. Save the file as assignment03yourlastname.py
Python program named "YourMuseumID_Exhibits.py" focusing on museum exhibit data: You have a list of dictionaries representing exhibits in a museum. Each dictionary contains the exhibit name, the number of artifacts on display, and the historical era it covers. Perform the following tasks: (a) Calculate and display the total number of artifacts on display for all exhibits in the museum. (b) Identify and display the exhibit with the highest number of artifacts on display. (c) Implement a function that takes a user-input exhibit name and searches for it in the list. If found, display the number of artifacts on display and the historical era it covers; if not found, print a message indicating that the exhibit is not in the museum. (d) Implement a sorting algorithm of your choice to sort the exhibits based on the number of artifacts on display in descending order and display the sorted list. Make sure to incorporate functions for each task and display the results in the main function with…

ASSIGNMENT REQUIREMENTS This assignment requires a dictionary of state abbreviations and their capital cities. The abbreviations are the keys and the state capitals are the values. Start by entering data for any four states of your choice. Then, report this count but use a function to get the count. Use a while loop to add more abbreviations and capitals. The loop should continue until the user presses Enter when prompted for an abbreviation. Inside the while loop: If the state entered is already in the dictionary, report its capital. If it is not in the dictionary, prompt the user to enter the capital for that state and add it to the dictionary After the while loop ends: Report again the count of the number of states in the dictionary. Using another loop and the items() method, display all the state abbreviations and their capitals. In the same Python program write this code, although it has nothing to do with the states code. Using a dictionary comprehension, create a…
