Implement the following function in the PyDev module functions.py and test it from a PyDev module named :

def gym_cost(cost, friends):
    """
    -------------------------------------------------------
    Calculates total cost of a gym membership. A member gets a
    discount according to the number of friends they sign up.
        0 friends: 0% discount
        1 friend: 5% discount
        2 friends: 10% discount
        3 or more friends: 15% discount
    Use: final_cost = gym_cost(cost, friends)
    -------------------------------------------------------
    Parameters:
        cost - a gym membership base cost (float > 0)
        friends - number of friends signed up (int >= 0)
    Returns:
        final_cost - cost of membership after discount (float)
    ------------------------------------------------------
    """

Sample testing:

Gym membership cost: $50
Number of friends signed up: 2

Your membership cost is $45.00

OUTPUT:

Raw_code:

#function defintion of gym_cost
def gym_cost(cost,friends):
#if the friends is 0 no discount
if(friends==0):
final_cost=cost+0
#if the friends is equal to 1 you get 5% discount
elif(friends==1):
final_cost=cost-(cost*0.05)
#if the friends is equal to 2 you get 10% discount
elif(friends==2):
final_cost=cost-(cost*0.1)
#if the friends are greater than or equal to 3 15% discount
elif(friends>=3):
final_cost=cost-(cost*1.5)
#returning final_cost
return final_cost
#a gym membership base cost
cost=float(input("Gym membership cost:$"))
friends=int(input("Number of friends signed up:"))
#if the cost is greater than 0 and the friends are greater than equal to zero
if(cost>0 and friends>=0):
#calling the gym_cost wuth parameters(cost,friends)
final_cost=gym_cost(cost,friends)
#printing the final cost
print("Your membership cost is $",final_cost)

Note:I done this program in python IDLE due to unavailable of PyDev

Kernal Modul Programing Quenstion : Implement the following 4 conditions in kernel module programming. 1. Implement a timer module using the timer function provided by the file LINUX/timer.h 2. In module_init, the timer is initialized using setup_timer and called mod_timer to start the timer. 3. Call back function my_timer_callback when timer expires. 4. When you remove a module, delete the timer.

Write the MIPS assembly codes to implement the following function: copy a block of words from one address to another. Assume that the starting address of the source block be in register $t1 and that the destination address be in $t2. The instruction also requires that the number of words to copy in $t3 (which is >0, that means how many words are needed to copy). Furthermore, assume that the values of these registers as well as register $t4 can...

Using your solution or your instructor's solution from the Module 8 ungraded practice exercise, implement a unit test for the Pair class by adding a main method. Create three small constituent classes (I created PeanutButter, Jelly, and Mustard classes) and insert various combinations of them into an array of Pair objects. Thoroughly test the equals(), hashCode(), and toString() methods from the Pair class with your main method. Note: override the toString() method in each of your constituent classes so they...

Design, implement, and fully test a Python3 function that converts a number to words (words_from_number(number: int)). It should expect to be passed a natural number (such as 12345) and return the corresponding words (i.e., “twelve thousand three hundred forty-five”). Since Python integers can grow arbitrarily large, your code should be flexible, handling at least 20 digits (realistically, it’s just as easy up to 30 digits). Spell everything correctly, and use correct punctuation (hyphens for forty-five and thirty-seven, no commas or...
