Write a Python program that prompts the user to enter grades to a list, alist (which is initiallyempty), and calculate the sum and average of the entered grades. The user will continueentering grades until he/she enters the sentinel value -1.Important Notes:- Grades are in the range from 0 to 20.You should use the while loop to input the gradesYou should print the final list, the sum, and the average (rounded to two figures).One of the grades should be the last digit of your ID +10. For example, if your IDnumber is 020787521426, then one of the entered grades should be 16 (6+10)You should include screenshots of the code and the output.Your program should have an output like the following:In case no grades have been entered, the output should be:Enter grades to calculate their average, -1 to stop entry: -1No grades have been entered!In case of entering some grades, the output should be:Enter grades to calculate their average, -1 to stop entry: 13Enter another grade, -1 to finish: 12Enter another grade, -1 to finish: 18Enter another grade, -1 to finish: -1[13, 12, 18]The Sum of the entered grades is: 43The Average of the entered grades is: 14.33

Pizzas: Think of at least three kinds of your favorite pizza. Store these pizza names in a list, and then use a for loop to print the name of each pizza. Modify your for loop to print a sentence using the name of the pizza instead of printing just the name of the pizza. For each pizza you should have one line of output containing a simple statement like I like pepperoni pizza. Add a line at the end of your program, outside the for loop, that states how much you like pizza. The output should consist of three or more lines about the kinds of pizza you like and then an additional sentence, such as I really love pizza!

Monthly Sales: Create a program that reads the total monthly sales for an entire year. The program outputs the average sales of the year, the names of the months above this average, and the names of the months below the average. Use a list to store the names of the months in a year, and use another list to store of the total sales for each of those months.
Transcribed Image Text Implement the following to search a letter in a list. a) Create a list named vehicles: car, Truck, boat, PLANE. b) Request a user input for a search letter. c) Use the decision structure in a for loop to search all the items which contains the input letter (ignoring case) in the list. d) Print the item and its position in vehicles if it exists. Otherwise, print the statement indicating it does not contain the letter to search. e) Print the error message if more than one letter is entered. Example Output 1 Vehicles = i'car', 'Truck', 'boat', 'PLANE’] Enter a search letter: a car contains 'a' and it is in position 0. Truck does not contain 'a'. boat contains 'a' and it is in position 2.

Write a complete program to generate a username based on a user's first and last name. Part One: Get a Valid First and Last Name ask the user for and read in their first and last name use a loop to validate the first name: it must be at least one character long and it must start with a letter use a loop to validate the last name: it must not contain any spaces Hint: use a nested loop. The outer loop will iterate until there is valid input. The inner loop will check each character in the String to see if any of them are whitespace. Part Two: Generate a Username generate a two-digit random number (i.e., a random number between 10 and 99, inclusive) create a username that is the following data concatenated: the first letter of their first name in lower case the first five characters of their last name in lower case; if the name is shorter than five characters, use the whole last name the two-digit number output the username to the user Additional Coding Requirements code…

In this lab, you write a while loop that uses a sentinel value to control a loop in a Python program. You also write the statements that make up the body of the loop. The source code file already contains the necessary assignment and output statements. Each theater patron enters a value from 0 to 4 indicating the number of stars that the patron awards to the Guide’s featured movie of the week. The program executes continuously until the theater manager enters a negative number to quit. At the end of the program, you should display the average star rating for the movie. Instructions Make sure the file MovieGuide.pyis selected and open. Write thewhile loop using a sentinel value to control the loop, and also write the statements that make up the body of the loop. Execute the program by clicking the Run button at the bottom of the screen. Input the following as star ratings: 0, 3, 4, 4, 1, 1, 2, -1 Ensure that the average output is correct.
