Write a program that reads student information from a text file, then creates a text file that records the course grades of the students and a final grade. Each row of the .txt file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student, each separated by a space. A sample of the student information is provided in StudentInfo.txt below. Assume the number of students is at least 1 and at most 20.
The program performs the following tasks:
• Read the file name of the .txt file from the user.
• Open the .txt file and read the student information using readline() or readlines().
• Compute the average exam score of each student.
• Assign a letter grade to each student based on the average exam score in the following scale:
◦ A: 90 =< x
◦ B: 80 =< x < 90
◦ C: 70 =< x < 80
◦ D: 60 =< x < 70
◦ F: x < 60
• Output the first names, last names, exam scores, and letter…
A java file that reads a text file, in.txt, that contains a list of positive integers a positive integer) separated by spaces and/or line breaks. After reading the integers, the program must recursively figure out if the list of integers includes two equal integers. If the list includes two equal integers, the program prints out Yes. Otherwise, the program prints out No. Assume that in.txt contains at least 2 integers. It is important that your program be named Two and that the input file is named in.txt.
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
the output is:
hello 1 cat 2 man 2 hey 2 dog 2 boy 2 Hello 1 woman 1 Cat 1
Note: There is a newline at the end of the output, and input1.csv is available to download. use "import csv" in code.

- Write a program that reads all words from a file and saves them in a data structure. Then, it prints out the word set in alphabetical order.arrow_forwardFor 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…arrow_forwardWrite a program that reads words from a file (filename given as a string parameter) and prints the occurance of each word(case insensitive). And print the words in alphabetical order. For example, if the file contains text Love is free free is love then the function should print free:2 is:2 love:2 def count_word(filename): # YOUR CODE HERE raise NotImplementedError()arrow_forward
- Write a program that first reads in the name of an input file and then reads the input file using the file.readlines() method. The input file contains an unsorted list of number of seasons followed by the corresponding TV show. Your program should put the contents of the input file into a dictionary where the number of seasons are the keys, and a list of TV shows are the values (since multiple shows could have the same number of seasons). Sort the dictionary by key (least to greatest) and output the results to a file named output_keys.txt. Separate multiple TV shows associated with the same key with a semicolon (;), ordering by appearance in the input file. Next, sort the dictionary by values (alphabetical order), and output the results to a file named output_titles.txt. Ex: If the input is: file1.txt and the contents of file1.txt are: 20 Gunsmoke 30 The Simpsons 10 Will & Grace 14 Dallas 20 Law & Order 12 Murder, She Wrote the file output_keys.txt should contain: 10: Will…arrow_forwardWrite a program that first reads in the name of an input file and then reads the input file using the file.readlines() method.
