Step by step
Solved in 2 steps
- Word FrequencyWrite a python program that reads the contents of a text file. The program should create a dictio-nary inwhich the keys are the individual words found in the file and the values are the number of timeseach word appears. For example, if the word “the” appears 128 times, the dictionary wouldcontain an element with 'the' as the key and 128 as the value. The program should eitherdisplay the frequency of each word or create a second file containing a list of each word and itsfrequency.File Encryption and DecryptionWrite a program that uses a dictionary to assign “codes” to each letter of the alphabet. Forexample:codes = { ‘A’ : ‘%’, ‘a’ : ‘9’, ‘B’ : ‘@’, ‘b’ : ‘#’, etc . . .}Using this example, the letter A would be assigned the symbol %, the letter a would beassigned the number 9, the letter B would be assigned the symbol @, and so forth.The program should open a specified text file, read its contents, then use the dictionaryto write an encrypted version of the file’s contents to a second file. Each character in thesecond file should contain the code for the corresponding character in the first file.Write a second program that opens an encrypted file and displays its decrypted contentson the screen. in phytonIn Python Write a program that reads movie data from a CSV (comma separated values) file and output the data in a formatted table. The program first reads the name of the CSV file from the user. The program then reads the CSV file and outputs the contents according to the following requirements: Each row contains the title, rating, and all showtimes of a unique movie. A space is placed before and after each vertical separator ('|') in each row. Column 1 displays the movie titles and is left justified with a minimum of 44 characters. If the movie title has more than 44 characters, output the first 44 characters only. Column 2 displays the movie ratings and is right justified with a minimum of 5 characters. Column 3 displays all the showtimes of the same movie, separated by a space. Each row of the CSV file contains the showtime, title, and rating of a movie. Assume data of the same movie are grouped in consecutive rows. Ex: If the input of the program is: movies.csv and the contents…
- In Java programming Write the code to print out a customer report. Your code must read each customer from a file, populate the object, place the object in a linked list, and display the data from the linked list. Use the customer object name from Customer customer = new Customer ( “ customer name” ); Assume you have opened a file and read a line into the customer object. Write the signature line for this method Write the line of code that will write the object to a linked list Write the line of code that will print the customer object properties. Be sure to include a textual description of each property.Word IndexWrite a python program that reads the contents of a text file. The program should create a dictionary inwhich the key-value pairs are described as follows:Key. The keys are the individual words found in the file.576Values. Each value is a list that contains the line numbers in the file where the word (thekey) is found.For example, suppose the word “robot” is found in lines 7, 18, 94, and 138. The dictionarywould contain an element in which the key was the string “robot”, and the value was a listcontaining the numbers 7, 18, 94, and 138.Once the dictionary is built, the program should create another text file, known as a word index,listing the contents of the dictionary. The word index file should contain an alphabetical listingof the words that are stored as keys in the dictionary, along with the line numbers where thewords appear in the original file. Figure 9-1 shows an example of an original text file(Kennedy.txt) and its index file (index.txtComplete this C++ code with the following requirements: Write a program that will allow a user to enter students into a database. The student information should include full name, student ID, GPA and status. The program should allow delete any student based on student ID. Program must use linked list. No vectors or arrays. C++. # include<iostream>using namespace std;class Node{ string full_name, status; int studentID; float GPA; Node* next;};Node* head= new Node();bool check (int x){ if(head==NULL){ return false; } Node* t=new Node(); t=head; while(t!=NULL){ if(t->studentID==x){ return true; t=t->next; } } return false;}void insert(int studentID, string full_name, string status, float GPA){ if(check(student_id)){ cout<<"Student already exists in the record"<<endl; return; } Node *t=new Node(); t->studentID=studentID; t->full_name=full_name;…

Column 3 displays all the showtimes of the same movie, separated by a space.Topical Information Use C++. This lab should provide you with practice in file handling, stream formatting, and some string manipulation. Classes might come in handy, too. Program Information Write a program that reads a list of enrollments from a file and prints a class roster for the teacher. Make the class roster line up as neatly as you can and still fit on the screen. You can choose the actual values to use for your data. Make sure to do enough sets of data to well test your program! (Empty data set, normal data set, data with large values, data with short values, etc.) Also, your program can't know ahead of time how many people are enrolled in the class... Don't forget to read the file's name from the user and protect your program against any errors that may occur during the opening of the file. Try to use functions to break up the program into more manageable pieces. As an example, you might have the data file contain: # name # student number # address1 # address2 # phone number…C++ Programing Create an application to keep track of a list of students and their grades in a data structures course using a linked list. You should use the C++ STL library. You need to create a class called student that contains 2 data members: name and grade and then create a linked list of objects of this class. The application should allow the user to add a student, remove a student, update the grade for a student, and search for a student. Please separate each file in your answer so it can be understood well.
- Write the following code in C Write a program that creates the following struct (you can give it whatever name you want): char name[100]; int age; float weight; Create the following menu system: Add a Record Display All Records Quit When the user selects (1) you will prompt them for a name, age, and weight. You will insert the record into the linked list which will be alphabetically ordered by name (first letter of full name). When the user selects (2) you will display all records currently in the list. This program will not use an array, but it will use a linked list of structs. The program will allow for an unlimited number of records. The only limit will the amount of available RAM.The program, word_frequency, counts the number of occurrences of words in a document. The program takes a filename as a parameter and performs the task. Get the program to run using the attached text file called document.txt. The file contains a piece of text. After you run the program and understand it's logic, modify word_frequency.py to use a binary search tree instead of a dictionary. Tasks: 1. Import a binary search tree 2. Change the filename in the program to reflect the change(s) made Python Only and no other coding languages. Import the module first before running it. Please show output when done. (build off of this file and try not to change too much) word_frequency.py: import sysfilename = sys.argv[1] freq = {}for piece in open(filename).read().lower().split():# only consider alphabetic characters within this pieceword = ''.join(c for c in piece if c.isalpha())if word: # require at least one alphabetic character freq[word] = 1 +…C++: You will create a header file with implementation that performs the task. Together with the header and implementation, you create a test program whose main function demonstrates that your functions work as they should. Two files, A and B which they are sorted. The files contain Numbers. Based on the files, create a third file let calles it C . that file C is going to contain all the elements in sorted order from both files A and B. This algorithm is called a merge..
