Task 5: Unscramble You will write a program that takes in 2 files: a dictionary file and a file listing jumbled words. Your binary will be called unscramble and will be run using unscramble The file contains a bunch of scrambled words, one word per line. Your job is to print out these jumbles words, 1 word to a line. After each jumbled word, print a list of real dictionary words that could be formed by unscrambling the jumbled word. The dictionary words that you have to choose from are in the file. As an example, the starter package contains two sample input files and the result should look as follows. The order that you display the dictionary words on each line can be different; however, the order that you print out the jumbled words should be identical to the order in your input. The sample out below is skipping a few lines to save handout space (your output must not omit these lines). nwae: wean anew wane eslyep: sleepy rpeoims: semipro imposer promise ettniner: renitent.…
Write a program that opens a specified text file then displays a list of all the unique words found in the file. Hint: Store each word as an element of a set. 5. Word Frequency Write a program that reads the contents of a text file. The program should create a dictio- nary in which the keys are the individual words found in the file and the values are the number of times each word appears. For example, if the word "the" appears 128 times, the dictionary would contain an element with 'the' as the key and 128 as the value. The
Phyton: Program 6: Write a program that allows the user to add data from files or by hand. The user may add more data whenever they want. The print also allows the user to display the data and to print the statistics. The data is store in a list. It’s easier if you make the list global so that other functions can access it. You should have the following functions: · add_from_file() – prompts the user for a file and add the data from it. · add_by_hand() – prompts the user to enter data until user type a negative number. · print_stats() – print the stats (min, max, mean, sum). You may use the built-in functions. Handling errors such as whether the input file exist is extra credit. To print a 10-column table, you can use the code below: for i in range(len(data)): print(f"{data[i]:3}", end="") if (i+1)%10==0: print() print() Sample run: Choose an action 1) add data from a file 2) add data by hand 3) print stats 4)…
#program should be wrote in python with comments please. Write a program that reads the contents of a text file. The program should create a dictio-nary in which the keys are the individual words found in the file and the values are the number of times each word appears. For example, if the word “the” appears 128 times, the dictionary would contain an element with 'the' as the key and 128 as the value. The program should either display the frequency of each word or create a second file containing a list of each word and its frequency.
In Java Oleae nust read a file A photographer is organizing a photo collection about the national parks in the US and would like to annotate the information about each of the photos into a separate set of files. Write a program that reads the name of a text file containing a list of photo file names. The program then reads the photo file names from the text file, replaces the "_photo.jpg" portion of the file names with "_info.txt", and outputs the modified file names. Assume the unchanged portion of the photo file names contains only letters and numbers, and the text file stores one photo file name per line. If the text file is empty, the program produces no output. Ex: If the input of the program is: ParkPhotos.txt and the contents of ParkPhotos.txt are: Acadia2003_photo.jpg AmericanSamoa1989_photo.jpg BlackCanyonoftheGunnison1983_photo.jpg CarlsbadCaverns2010_photo.jpg CraterLake1996_photo.jpg GrandCanyon1996_photo.jpg IndianaDunes1987_photo.jpg LakeClark2009_photo.jpg…

Complete the following function according to its docstring description. Notes: • report is a file open for reading, not a string representing the name of a file. • the method str.strip() may come in handy! 1 from typing import TextIO def every_second_line(report: TextIO) -> list[str]: """Return a list containing every second line (with leading and trailing whitespace removed) in report, starting with the first line.
IN C++ 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. Hints: Use the find() function to find the index of a comma in each…
The python function first_words takes one parameter, fname, the name of a text file, and returns a list containing the first word from each line of the file. For example, if the file contents are: apples are red bananas are yellow limes are green then the list ["apples", "bananas", "limes"] should be returned.NOTE: You may assume the file will contain no blank lines.BIG HINT: If line is a string representing a line of text (inside of a for loop!), then L = line.split() creates a list of the words in the line.
In C++, you are going to write a program that implements a doubly linked list. The data must be read from the files and you can put the file names in your program. Letters.txt contains 26 English Letters: Copy the following exactly as it is into own .txt file to test: ABCDEFGHIJKLMNOPQRSTUVWXYZ Sequence.txt contains a list of numbers. Copy the following exactly as is into another .txt file3,-3,19,-19,18,1,-2,3,-18,17,1,-3,-13,14 You need to 1. Create a doubly linked list by reading the 26 letters from Letters.txt. 2. Sequence.txt file contains a sequence of relative letter positions. The initial position is at the beginning of the list which is ‘A’. The first number in the sequence is ‘3’. So the current position will move forward for three steps. Then the first letter to output is ‘D’ and now the current position is at ‘D’ as well. The second number in the sequence is ‘-3’. Then the second letter to output is the third element backward from the current position which is ‘A’. You…

Python please: Given the input file input1.csv write a program that first reads in the name of the 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 in a sorted list. The contents of the input1.csv are: hello,cat,man,hey,dog,boy,Hello,man,cat,woman,dog,Cat,hey,boy Example: If the input is input1.csv the output is: ['Cat', 'Hello', 'boy', 'boy', 'cat', 'cat', 'dog', 'dog', 'hello', 'hey', 'hey', 'man', 'man', 'woman'] Note: There is a newline at the end of the output.
