ow do I write a Python Program that must use a while loop that prompts the user to enter the first name and age of each friend. Each of these entries should be written to its own line in the text file (2 lines of data per friend). The while loop should repeat until the user presses Enter for the name. Then, the file should be closed and a message should be displayed. See Sample Output. SAMPLE OUTPUT Enter first name of friend or Enter to quit Denny Enter age (integer) of this friend 24 Enter first name of friend or Enter to quit Penny Enter age (integer) of this friend 28 Enter first name of friend or En

Using Python

Program - Python Write a program asking the user to keep entering in strings (ie names) until they enter the string "leave", at which point you’ll exit the loop and tell them how many times they entered the string "gold". This one requires that you use a loop and also keep a tally of the number of times they enter the string gold.

program4_1.pyWrite a program that prompts a dieter to enter in their caloric budget (as an integer) for the week. After accepting and storing that value, use a while loop to accept and process the caloric value for each meal (entered as an integer value). Within the while loop keep a running total of the caloric values of the meals entered and a count of the meals entered. Terminate the while loop when the dieter enters 0. After the while loop ends, print the count of meals entered and print a message (follow the examples in the example outputs) indicating whether the dieter's caloric total intake was at, above, or below their caloric budget. Printed output messages will vary based on input but related output should be formatted as in the example outputs. The ellipsis is being used to represent missing values that your program should also generate.

5. What will be the value of x after the following loop is executed? X = 0 For i = 1 To 2 For j = 1 To 3 X = X +i* j Next j Next i

program4_1.pyWrite a program that uses a for loop and the range function to examine all integers from 999 down to zero. Code in the loop should print multiples of 40 on one line separated by spaces, but with only six on each line. See Required Output. Use a counter to determine when six multiples have been printed. A counter is a variable that is initialized to zero and incremented by one when the event to be counted occurs. Include pseudocode.

True or False: When asking user for data, we can always turn an algorithm that uses a user-confirmation loop into one that uses a sentinel loop. Select one: a. False b. True

Write a for loop that displays all of the odd numbers, 1 through 49.

Summary 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. 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. Instructions Make sure the file MovieGuide.py is 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 must be written with this code: """ MovieGuide.py This program allows each theater patron to enter 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...

What will this For loop will print on the screen? FOR x = 1 TO 5 Print x * x Next x

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.
