- • Use a while loop • Use multiple loop controlling conditions • Use a boolean method • Use the increment operator • Extra credit: Reuse earlier code and call two methods from main Details: This assignment will be completed using the Eclipse IDE. Cut and paste your code from Eclipse into the Assignment text window. This is another password program. In this case, your code is simply going to ask for a username and password, and then check the input against four users. The program will give the user three tries to input the correct username-password combination. There will be four acceptable user-password combinations: • alpha-alpha1 • beta-beta1 • gamma-gamma1 • delta - delta1 If the user types in one of the correct username-password combinations, then the program will output: "Login successful." Here are a couple of example runs (but your code needs to work for all four user-password combinations): Username: beta Type your current password: beta1 Login successful. Username: delta Type…arrow_forwardYou need to write a loop that will repeat exactly 125 times. Which is the preferred loop construct to use?

O while loop checks the condition before the loop begins, whereas the do-while loop executes the body at least once before checking the condition. O while loop is used for counter-controlled and do-while, is used for a sentinel loop. O while loop is used for selection controlled and do-while is used for an infinite loop. O while loop is used for endless controlled control and do-while, is used for counter-controlled loop. Save All Ans Click Save and Submit to save and submit.

- Write a loop that asks the user “Do you want to repeat the program or quit? (R/Q)”. The loop should repeat until the user has entered an R or Q (either uppercase or lowercase).arrow_forwardIn the switch statement, we can use int type only for the control variables that are being tested in the loop condition. True Falsearrow_forwardTranscribed Image Text In this assignment, you will design a program in which you will ask the user to enter a number and use a while loop to see if the number entered by the user is a palindrome number or not. A palindrome number is a number which remains the same, even when the digits are reversed. For example: 121 is a palindrome number. 277 is not a palindrome number. Lab Procedure: 1. Prior starting of the work consider how to design the while loop: a. What would be the loop condition? b. What would be the stopping criteria? 2. Determine how to extract each digit. What are the variables and where to initialize the variables. 3. Test the application by hand-calculating several values and use the same values to validate the operationarrow_forward
- .. Code pleasearrow_forwardIn a loop when a condition is false you come out of the loop. However, interesting things happen when the condition is true and you remain in the loop. What kinds of interesting things happen discuss with arguments.arrow_forwardQuestion#2. The distance a vehicle travels can be calculated as fallout: Distance = Speed * Time For example, if a train travels 60 miles-per-hour for three hours, the distance [raveled is 120 miles. Write a program that asks for the speed of a vehicle (in miles-per-hour) and the number of hours it has traveled. It should use a loop to display the distance a vehicle has traveled for each hour of a time period specified by the user. For example, if a vehicle is traveling at 40 mph far a three-hour time period, it should display a report similar to the one chat follows: Hour Distance Traveled 1 90 2 100 3 150 Input Validation: Do not accept a negative number for speed and do not accept any value les than 1 for time traveled.arrow_forward
- Which loop should you use in situations where you want the loop to repeat until the boolean expression is false, but the loop should execute at least once?arrow_forwardWrite a while loop which prompts the user for the name of a drink and the cost. Add these new items to the drinks_dict. When the user enters "quit", exit the loop. Be sure to cast the value for the cost to a float. Spring Water 1.25 Sparkling Water 2.00 exit Use the values() method to access the values in drinks_dict. Use a loop to print out the values. Use the keys() method to access the keys in drinks_dict. Use a loop to print out the keys. Print the code and the output from the Python Shell. Compute the sum of all of the values for the drinks. Print out the sum. Print the code and the output from the Python Shell. Write a function named find_drink_function(0 that takes two parameters a dictionary and a key: If the key is in the dictionary, return True, otherwise return False. Call the function from within main with the following arguments: drinks_dict and "Tea". Assign the returned Boolean value to a variable found. Print out the value of found.
