- The __str__ method of the Bank class (in bank.py) returns a string containing the accounts in random order. Design and implement a change that causes the accounts to be placed in the string in ascending order of name. Implement the __str__ method of the bank class so that it sorts the account values before printing them to the console. In order to sort the account values you will need to define the __eq__ and __lt__ methods in the SavingsAccount class (in savingsaccount.py). The __eq__ method should return True if the account names are equal during a comparison, False otherwise. The __lt__ method should return True if the name of one account is less than the name of another, False otherwise.code: public class PasswordGeneratorAndStorage {/*** Adds an application to the applications ArrayList.

This program will contain an ArrayList of StudentGrades objects. The program will perform the following tasks: Create an instance of an ArrayList that will store three StudentGrades objects. Each element in the ArrayList represents student grades for a test (assessment). This means that each StudentGrades object stored by the ArrayList element represents the grades achieved by students for a single test. Prompt the user for the number of students in the class. The prompt text is: Enter the number of students in the course: [Keyboard Input] Add three new StudentGrades objects to the ArrayList. The StudentGrades objects should be populated with random values from 0 to 100. Use the enhanced for loop to print each of the StudentGrades objects to the console. Print a line containing the following text: “LAST ELEMENT BEFORE REMOVE:”. Print the value of the final element in the ArrayList under the heading.…

- Use the ArrayList class Add and remove objects from an ArrayList Protect from index errors when removing Practice with input loop Details: This homework is for you to get practice adding and removing objects from an ArrayList. The Voter class was used to create instances of Voters which held their name and a voter identification number as instance variables, and the number of instances created as a static variable. This was the class diagram: The constructor takes a string, passed to the parameter n, which is the name of the voter and which should be assigned to the name instance variable. Every time a new voter is created, the static variable nVoters should be incremented. Also, every time a new voter is created, a new voterID should be constructed by concatenating the string “HI” with the value of nVoters and the length of the name. For example, if the second voter is named “Clark Kent”, then the voterID should be “HI210” because 2 is the value of nVoters and 10 is the number…private static final List<Polynomial> polyList = new ArrayList<>(); //main here public static void main(String[] args) { processPolyList(); } //=============================================================================================== // method: fromFile / returns: Arraylist // description: Opens a file takes a String and tokenizes it into an ArrayList of of expressions //=============================================================================================== public static ArrayList<String> f# define stemmer functionstemmer = SnowballStemmer('english') # tokenise datatokeniser = TreebankWordTokenizer()tokens = tokeniser.tokenize(data) # define lemmatiserlemmatizer = WordNetLemmatizer() # bag of wordsdef bag_of_words_count(words, word_dict={}): """ this function takes in a list of words and returns a dictionary with each word as a key, and the value represents the number of times that word appeared""" for word in words: if word in word_dict.keys(): word_dict[word] += 1 else: word_dict[word] = 1 return word_dict # remove stopwordstokens_less_stopwords = [word for word in tokens if word not in stopwords.words('english')] # create bag of wordsbag_of_words = bag_of_words_count(tokens_less_stopwords) Use the stemmer and lemmatizer functions (defined in the cells above) from the relevant library to find the stem and lemma of the nth word in the token list.
