Write a Python program that reads each line of an input file called data.txt that consists of a keyword followed by a sequence of numbers separated by commas. If the keyword is UP, the numbers are sorted in increasing order, if the key word is DOWN; the numbers are sorted in decreasing order. The sorted sequence of numbers is saved in sorted.txt. For example, if the data.txt contains UP 25 35 30 40 30 DOWN 20 30 25 25 DOWN 35 45 40 15 16 18 The file sorted.txt will contain 25 30 30 35 40 30 25 25 20 45 40 35 18 16 15

Write a program that first reads in the name of an input file and then reads the file using the csv.reader() method. The file contains a list of words separated by commas. Your program should output the words and their frequencies (the number of times each word appears in the file) without any duplicates. Ex: If the input is: input1.csv and the contents of input1.csv are: hello,cat,man,hey,dog,boy,Hello,man,cat,woman,dog,Cat,hey,boy
Write a program that will read in a file of student academic credit data and create a list of students on academic warning. The list of students on warning will be written to a file. Each line of the input file will contain the student name (a single String with no spaces), the number of semester hours earned (an integer), the total quality points earned (a double). The following shows part of a typical data file: Smith 27 83.7 Jones 21 28.35 Walker 96 182.4 Doe 60 150 The program should compute the GPA (grade point or quality point average) for each student (the total quality points divided by the number of semester hours) then write the student information to the output file if that student should be put on academic warning. A student will be on warning if he/she has a GPA less than 1.5 for students with fewer than 30 semester hours credit, 1.75 for students with fewer than 60 semester hours credit, and 2.0 for all other students. The file Warning.java contains a skeleton of the…
Write a program to draw a quiz score histogram. Your program shouldread data from a file. Each line of the file contains a number in the range0-10. Your program must count the number of occurrences of each scoreand then draw a vertical bar chart with a bar for each possible score (0-10) with a height corresponding to the count of that score. For example,if 15 students got an 8, then the height of the bar for 8 should be 15.Hint: Use a list that stores the count for each possible score. An examplehistogram is shown below: o o D D0 1 2 3 4 5 6 7 8 9 10
Write a program in C++ that will let the user create a text file name NameRecord.txt and allow the user to input 5 name and 5 age in the file. The program will display the names listed in a file having the age correspond to the input of the user. Example. Enter name and age: Kim 25 Enter name and age: Jose 27 Enter name and age: John 25 Enter name and age: Anna 35 Enter name and age: Luis 29 Enter age to search: 25 OUTPUT: The following have age 25 Kim John *Using Iostream * With Screenshot
Python Create a program that reads the file (create a paragraph in a file). It should analyze each character of the file. For output, it should produce a well-formatted table indicating: The total number of printable characters The total number of capital letters The total number of lowercase letters The total number of numbers The total number of sentences (which end in a period) The total number of paragraphs (which end in a newline) Since the lab is an exercise in strings, you must use at least TWO different string methods to required information. And each stastic will need its own function.
IN PYTHON: Decrypting with ascii I have a file called 'dict.txt'. This file contains over 50,000 english words. One word from this file is used as a key (we do not know which one of course). Some have capital letters. I have another file called 'decrypt.txt' which is a file containing a string of numbers i must decrypt using a key found in the 'dict.txt'. This 'decrypt.txt' file message has length of 300. My question is, since i do not know which word (from the file with the 50,000+ words) is the key I must use to decrypt the other file, how do I write a function that: loops through all possible keys from 'dict.txt' to find the one that decrypts my file 'decrypt.txt' best? Somehow i must count how many 'words' are actual words to determine which key is best and then print my final decrypted message.
Write a python program that prompts the user for their favorite basketball team. It should be able to read the list of teams provided below in a file called favorite_teams.txt and check if their team is in that file. Teams in the file:JazzBullsMavericksSpursIf the team is in the file let the user know that their team is in the list of favorites. If the team is not in the file, add the team to the end of the file. Also, let the user know that their team will be added to the file.Sample Run in File:What is your favorite NBA team? Jazz [Enter]Your team Jazz is in the listFile before and after run: JazzBullsMavericksSpurs Sample Run not in File:What is your favorite NBA team? Pelicans [Enter]Your team Pelicans is not in the list. It will be added.File before run: JazzBullsMavericksSpursFile after run:JazzBullsMavericksSpursPelicans
For this assignment, you will write a Python program that uses a file named scores.txt to store sets of bowling scores for different dates. scores.txt should store the data so that each line has a month, day, and the scores the user earned on that date. As an example, scores.txt might look something like this: January 15 200 300 126 200 250April 20 125 100 May 17 300 100 215 The very first time your program starts, scores.txt should not exist (i.e. create it with Python code the first time the program runs). In your main function, continuously give the user the following five options: Quit the program. View all Scores. If the user selects this option, call a function named view_scores. This function should print the scores in a nicely formatted manner. For example: "On January 15, you scored 200, 300, and 126", etc.. Add a Score. If the user selects this option, call a function named add_score. This function should ask the user for a month, day, and as many scores as they want to…
Java Your program must read a file called personin.txt. Each line of the file will be a person's name, the time they arrived at the professor's office, and the amount of time they want to meet with the professor. These entries will be sorted by the time the person arrived. Your program must then print out a schedule for the day, printing each person's arrival, and printing when each person goes in to meet with the professor. You need to print the events in order of the time they happen. In other words, your output will be sorted by the arrival times and the times the person goes into the professor's office. In your output you need to print out a schedule. In the schedule, new students go to the end of the line. Whenever the professor is free, the professor will either meet with the first person in line, or meet with the first person in line if nobody is waiting. Assume no two people arrive at the same time. You should solve this problem using a stack and a queue. You can only…
Write a Python program that reads a text file called student.txt. The input text file contains student_ID, student_name, Quiz_grade as well as Test_grade for each student. Your program should read each student details from the file Then calculate the average of Quizzes and Tests marks Display the students’ details: Total number of students, total average, the total highest and lowest marks. The program should output the report into a file called output.txt. A sample of output text file is given below.
Suppose you are given a text file that contains the names of people. Every name in the file consists of a first name and last name. Unfortunately, the programmer that created the file of names did not guarantee that each name was on a single line of the file. Read this file of names and write them to a new text file sorted according to first name, one name per line. For example, if the input file contains Ed Marston Bob Jones Jeff Williams Fred Charles The output file should be Bob Jones Ed Marston Fred Charles Jeff Williams Use arrays to solve the problem.
Write a C program that reads a text file "My_book.txt" and counts the number of characters, words, and lines in the file. Then, the program should write these counts to a new file "My_book_info.txt" in the following format: Number of characters: [count] Number of words: [count] Number of lines: [count]
