The program should promptthe user for a filename and input the lines of textinto a list. The program then enters a loop in whichit prints the number of lines in the file and promptsthe user for a line number. Actual line numbersrange from 1 to the number of lines in the file. If theinput is 0, the program quits. Otherwise, theprogram prints the line associated with thatnumber.An example file and the program input and outputis shown below:example.txtLine 1.Line 2.Line 3.Enter the input file name: example.txt The file has 3lines.

This DNA test measures the various parts of the sequence and assigns them a letter. While the letters could be anything from A to Z, the only letters that matter for this test are the letters {A,B,C,D} all other letters can be ignored completely. A sample will be tested, given a length of time and then tested again. Each time the scientist will generate a line of data.

File redirection allows you to redirect standard input (keyboard) and instead read from a file specified at the command prompt. It requires the use of the < operator (e.g. java MyProgram < input_file.txt) True or False
True or FalseAs items are read from the file, the read position moves forward, toward the end of the file.
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.
