Lab 4.3 - Python Code (Optional) Critical Review In Python, you use the while statement to write a condition-controlled loop. The loop has two parts: (1) a condition that is tested for a true or false value, and (2) a statement or set of statements that is repeated as long as the condition is true A while loop can also be used for count-controlled loops Here is the general format of the while loop in Python: while condition: statemen statemen etc Since the while loop is a pre-test, it is important to initialize your loop control variable to a starting value so that the first iteration will be true As with all loops, be sure to change the loop control variable either by incrementing or asking a question. Help Video: lab4-3.wmv The goal of this lab is to convert the Bottle Return program to Python code Step1: Start the IDLE Environment for Python. Prior to entering code, save your file by clicking on File and then Save. Select your location and save this file as Lab4-3.py. Be sure to include the py extension. Step 2: Document the first few lines of your program to include your name, the date, and a brief description of what the program does Step 3: Start your program with the following code for main: #Lab 4-3 The Bottle Return Program #the main function def main): #calls main main () Step 4: Python only supports While loops, so endProgram must be initialized to 'no Under def main): , create a variable called endProgram and set it to 'no such as
