Python: Here's My Homework

Posted 04 June 2010 - 09:11 AM

Hi everyone am an undergraduate student at Portsmouth University, hampshire, United Kingdom. Please I need help with my Puthon coursework. Actually I've been re-taking my python programming unit since 1st semester of year 1 and still struggling to pass the unit. Please am asking if someone here with good knowlwdge of python can help me with my work. I will be forever greatful for the favour.

Here is the work to be completed

Program 2

Money. A company pays its salesman £10 commission for every product sold. If more than 50 products are sold in a week, each extra sale earns £15 commission. If more than 100 products are sold, each extra sale earns £20. Write a program to input the number of products sold and calculate and print out how much is earned.

Program 3

Marks. Write a program that processes a number of student’s marks. The first is an exam mark in the range 0 - 60, the second mark a coursework in the range 0 - 40. Write code that checks that each mark is valid, and asks the user to re-input the data if not valid. Then add the two marks together to form a mark out of 100, and assign it to either a fail, pass, merit, or distinction (Under 40 is a fail, 40 or above a pass, 60 or above a merit, 70 or above a distinction)

The program should make use of a loop to allow the user to process as many student marks as they choose

Program 4

Pizza. You have already written a ‘pizza’ program to calculate the ‘value’ of a pizza. Now rework it, so that it utilises 4 functions – the first validates that the pizza size is between 6 and 15 inches, the second validates a (positive) cost, the third calculates the area of the pizza, and the fourth calculates the cost per square inch.

The structure of the program will look like this:

def Pizza():
size = validateSize(“Enter diameter of pizza (6 – 15) : ”);
cost = validateCost()
area = calcArea(size);
unitCost = perSqInch(area);
print “A pizza”, size,”inches in diameter has a unit cost of £”, \
unitCost,”per square inch”;

# function validateCost – gets and returns a positive float value
def validateCost():
<you complete>

#function validateSize(prompt) - accepts a prompt from main program, and # asks user to input a valid size (6 – 15 inches). Returns a valid size
def validateSize():
<you complete>

#function calcArea accepts a ‘size’ parameter, calculates and returns the area
def calcArea(size):
<you complete>

#function perSqInch accepts parameters ‘area’ and ‘cost’, returns unitCost
def perSqInch(area, cost);
<you complete>

Program 5
Speed Gun. The speeding ticket fine policy in Podunksville is $50 plus $5 for every mph above the speed limit up to 90. Speeds over 90 are also fined an additional $200. Write a program to
- accept a value for the speed limit for the selected stretch of road
- then, within a loop:
- get the clocked speed of each car as it passes the radar gun (this value typed in each time by the user).
- calculate and print either that the speed was legal, or print the amount of the fine, or print an error message (Constraints: the speed radar cannot cope with speeds under 1 (car is stationary or reversing, or over 120 (outside technical capabilities). In either situation, print out an error message, but do not process it.)

Typical Output:

This program calculates a speeding fine

Enter the speed limit on this stretch(mph) : -50
- invalid speed limit -50, must be greater than 0
Enter the speed limit on this stretch(mph) : 50
- starting to process car data

Enter the clocked speed of the next car(mph) : 50
50 mph - within speed limit of 50
Process another car (y/n )? Y

Enter the clocked speed of the next car(mph) : 51
51 mph - exceeds speed limit of 50 mph. Fine is $55
Process another car (y/n ): y

Enter the clocked speed of the next car(mph) : 90
90 mph - exceeds speed limit of 50 mph. Fine is $250
Process another car (y/n ): y

Enter the clocked speed of the next car(mph) : 91
91 mph - exceeds speed limit of 50 mph. Fine is $455

Process another car (y/n ): y
Enter the clocked speed of the next car(mph) : 150
Speed 150 is outside working parameters of the equipment

Process another car (y/n ): n
End of speed trap.

Call the post a joke or a test and walk away with some pride intact.

If you've taken this for a while and are still struggling, Computer Science may not be for you. From here on it only gets more challenging.
