In the Python programming language: Create a program that stores the names of the user's friends in a list. The program should allow a user to add friends to the list, remove friends from the list, and display the entire list of friends. A menu should be created that displays those options like so: 1 - View all 2 - Add Friend 3 - Remove Friend 4 - Exit The program should continue in a loop until the user selects exit. Hint: Use a function for each menu selection.

In Python FormA. Create a sorted_grades application that can store up to 10 grades in order from highest to lowest in a list. The application should display a menu of options, which include “Enter a grade”, “Delete a grade”, “Display lowest grade”, “Display highest grade”, “Show grades”, and “Quit”. The list should initially contain all zeros (0).The algorithm for entering a grade is similar to:1. Find the appropriate position for the grade so that all grades are still in order from highest to lowest.2. Insert the grade3. Make certain that length of list remains the sameThe algorithm for deleting a grade is similar to:1. Find the element containing the grade to delete.2. If list empty tell user they can’ delete and if grade doesn’t exist, inform user no grade has been found.3. Use del function. Make certain the length doesn’t change and last element =0
The function last_words in python takes one parameter, fname, the name of a text file, and returns a list containing the last 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 ["red", "yellow", "green"] 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 a for loop!), then L = line.split() creates a list of the words in the line. For example: Test Result L = last_words("wordlist1.txt") print(L) ['happy', 'sad', 'angsty', 'euphoric', 'maudlin']
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 Python: Write a program that performs the following: Defines two sets s1, and s2, where each of them contain the following: s1 = {1,2,4,5,6} s2= {1,3,4,7} Provides a menu with the following options: Union Intersection Difference Symmetric difference Display sets Exit The program stops once the user enters 6 (chooses to exit). When the user selects any of the other options, the corresponding operation is performed and the result is displayed. Please refer to the attached code which contains an example on how to implement a menu. Notes: I will leave the code organization for you, at this stage, you should be able to organize your program into functions in a proper way For the third operation (difference) find s1-s2. For the remaining operations it does not matter (for example, s1 union s2 is same s2 union s1)
You have been asked to write a program that will allow your client Tigger Movie Rentals to keep track of their inventory.For the purposes of this program, we will assume they only have one copy of each movie in the inventory.Your program should:Continue until the user wishes to exit the program (use a loop)Give the user 4 options from a menu:list – list all moviesadd – add a moviedel – delete a moveexit – exit the programExample (does not have to match this exactly): Command Menu list - List all movies add - Add a movie del - Delete a movie exit - Exit program If the user enters an option other than those 4, provide an error message and ask the user to re-enter the selectionThe list of movies in inventory will be stored in a file named movies.txt (a starting version of the file is provided). You can assume the file is stored in the same directory as the .py file. When the list option is selected, a list of the current inventory will be displayed to the screenExample (does not have to…
IN PYTHON, 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 The average is 43.0
Please do this in Python: 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.

1. Continuously prompt the user to enter a word until the user enters q. 2. Store the entered words in a list 3. Making use of the random module, your program should call word_selection() that randomly selects a word from the list and prints it 4. Include the guard for the main function: if __name__ == '__main__': main() Example: Enter a word (or ‘q’ to quit): Wallaby Enter a word (or ‘q’ to quit): Dingo Enter a word (or ‘q’ to quit): Platypus Enter a word (or ‘q’ to quit): q Wallaby
