Question

In this assignment we are asking the user to enter two number values, the starting and ending numbers for our application. Having these values, we then construct a loop that will increment by one (1) from the starting number through (and including) the ending number. Within this loop we will check the current value of our number to see if it is evenly divisible by 3, then by 5, and then by both 3 and 5. We will output all values to the screen and note which are divisible by "3", "5", or "Both."

Important: As part of this assignment the checking to see if a value/number is evenly divisible by 3, by 5, or by both is to be handled within a function or set of functions. How you implement this is up to you. But your project needs to implement at least one function.

For example, if the user enters 1 for the starting number and 100 for the ending, we will loop through all values of 1 through 100, one at a time. For the first value we will print "1". For the next "2". But for three we will print "3 - 3". For five "5 - 5". But for 15 we will print "15 - Both".

This should not be difficult work. They key to this is understand for each value whether it is evenly divisible by 3 or 5 or by both 3 and 5. This requires that you use the Modulo operator in Python. All programming languages have a modulo operator.

When complete, your output should be as pictured below:

In this example, my starting value is 1 and the ending value is 25:

In this example, my starting value is 15 and the ending value is 30:

• You must have a set of comments at the top of the program that identifies the programmer, date, and name of the program file. Furthermore, you must provide a description of what this program is and what it does. Each of these comments must be on individual lines.
• The following two pieces of data will be entered by the user: starting number and ending number
• Using the entered data, you will loop through this range of values one at a time.
• For each value in your range you will determine if it is evenly divisible by 3, by 5, or by both 3 and 5.
• The value—in all cases—will be output to the screen. But if it is evenly divisible by 3, 5, or both you will note that in the output.
• You must demonstrate your knowledge of functions by creating at least one function: to perform the check for whether the current value is evenly divisible by 3, 5, or both. You can create as many functions as you wish, but you must have at least one function.

def divisible_by_3(num):
    if num % 3 == 0:  # If divisible by 3 return true or false
        return True
    else:
        return False

def divisible_by_5(num):
    if num % 5 == 0:  # If divisible by 3 return true or false
        return True
    else:
        return False

    # Ask user to enter starting and ending point
    starting_value = int(input('Enter starting value: '))

    for i in range(starting_value, ending_value + 1):
