Tasks

Create a project folder username_a05. Place all your tasks python files(t01.py , t02.py ,t03.py) and the testing file testing.txt inside this folder. Upon completing your tasks, export your projrct folder to username_a05.zip file, validate it, and submit it to the dropbox by the due date.

Write and test the following function:
```
        
def factorial(num):
    """
    -------------------------------------------------------
    Calculates and returns the factorial of num.
    Use: product = factorial(num)
    -------------------------------------------------------
    Parameters:
        num - number to factorial (int > 0)
    Returns:
        product - num! (int)
    ------------------------------------------------------
    """

      
```
Add the function to a Python module named functions.py. Test it from .

In mathematics, the notation n! represents the factorial of the non-negative integer n. The factorial of n is the product of all the non-negative integers from 1 to n. Examples:

7! → 1 × 2 × 3 × 4 × 5 × 6 × 7 → 5040
4! → 1 × 2 × 3 × 4 → 24

The function must use a for loop.

The function does not ask for input and does no printing - that is done by your test program.

Sample execution:
```
          factorial(7)
        
```
```
5040
```
```
          factorial(1)
        
```
```
1
```
Test the function with three different sets of parameters.

Write and test the following function:
```
        
def calories_burned(per_minute, minutes):

      
```
Add the function to a Python module named functions.py. Test it from .

Running on a treadmill burns a certain number of calories. calories_burned prints a table of the number of calories burned every five minutes given the number of calories burned per minute (per_minute) an the total number of minutes run (minutes). Align the results and print with 1 decimal acurracy for the calories burned as shown in the example execution.

Provide the function docstring (documentation) following the CP104 style.

The function must use a for loop.

The function does not ask for input.

Sample execution:
```
        calories_burned(4.1, 30)
      
```
```
  5:  20.5
 10:  41.0
 15:  61.5
 20:  82.0
 25: 102.5
 30: 123.0
```
Test the function with three different sets of parameters.

Write and test the following function:

        
def range_total(start, increment, count):
    """
    -------------------------------------------------------
    Uses a for loop to sum count values from start by increment.
    Use: total = range_total(start, increment, count)
    -------------------------------------------------------
    Parameters:
        start - the range start value (int)
        increment - the range increment (int)
        count - the number of values in the range (int)
    Returns:
        total - the sum of the range (int)
    ------------------------------------------------------
    """

Add the function to a Python module named functions.py. Test it from .

The function must use a for loop.

Example: the sum of 5 values starting from 2 with an increment of 2 is:
2 + 4 + 6 + 8 + 10 → 30

The function does not ask for input and does no printing - that is done by your test program.

Sample execution:

        range_total(1, 1, 5)

        range_total(2, 2, 5)

Test the function with three different sets of parameters.
