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.
JAVA PPROGRAM Write a program that prompts the user to enter a file name, then opens the file in text mode and reads names. The file contains one name on each line. The program then compares each name with the name that is at the end of the file in a symmetrical position. For example if the file contains 10 names, the name #1 is compared with name #10, name #2 is compared with name #9, and so on. If you find matches you should print the name and the line numbers where the match was found. While entering the file name, the program should allow the user to type quit to exit the program. If the file with a given name does not exist, then display a message and allow the user to re-enter the file name. The file may contain up to 100 names. You can use an array or ArrayList object of your choosing, however you can only have one array or ArrayList. Input validation: a) If the file does not exist, then you should display a message "File 'somefile.txt' is not found." and allow the…

num.txt is a file that contains a list of scores. num.txt 10 25 36 45 89 42 54 create a program that reads the scores from num.txt file one line at a time. The program should display their total and average. since the number of scores is unknown, the program must keep looping until readline is blank. Sample Output: There are 7 scores The total is 301 T he average is 43.0
C++ Create a program that reads a file containing a list of songs and prints the songs to the screen one at a time. After each song is printed, except for the last song, the program asks the user to press enter for more. After the last song, the program should say that this was the last song and quit. If there were no songs in the file to begin with, the program should say that there are no songs to show and quit. The program should begin by asking the user for the name of the input file. Each song consists of a title, artist, and year. In the file, each song is given on three consecutive lines. Create this program using a class Song.

C++ Programming. Associative and unordered associative containers. Associative containers (set, map, multiset, multimap). • When executing a given task, the input values must be read from a text file. Task : Create a program that deletes a set of elements from a single word of a given string type and creates a second set of elements that consist of a single word, and also displays it on the screen.
Please I really need help with this question it is confusing me a lot I don't understand how should I start, Also can you please attach the TEXT FILE Screenshot. PLEASE! Write a program that allows the user to navigate lines of text in a file. The program should prompt the user for a filename, read the file and input the lines of text into a list. The program then enters a loop in which it prints the number of lines in the file and prompts the user for a line number. Actual line number range from 1 to the number of lines in the file. If the input is 0, the program quits. Otherwise, the program prints the text associated with that number. You must also run the script and provide a screenshot of the output along with the textfile.

C++ A teacher is requiring her students to line up in alphabetical order, according to their first names..For example, in one class Chapel, Christine would be at the front and Uhura, Nyota would be last. The program will get the names from a file. The names should be read in until there is no more data to read. The program should prompt the user for the file name and read the data from the file. A suitable file of names (List of Random Names) is provided on Moodle. Note that these names might include spaces; handle your input accordingly. The expected output is two names; do not show the entire file (or you will regret that code when you do the associated programming quiz that processes thousands of names). Do not use arrays or sorting for this problem.
