Question

Lab 7.4- Arrays and Python Code (Optional) Critical Review In Python, arrays are native objects called lists List index starts at 0 (unlike Raptor). The following is a method used when you kow the elements of the array even number [2, 4, 6, 8, 10] You can use the print statement to display an entire list, as shown here: print (even nunbers) The follorwing is a method used when you do not know what the elaments should be, but you lnow the size. numbers= [0] * 5 A loop can also be used to print the elements of the aray. An example is as follows: A for in loop for n in numbers print (n A while loop index = 0 while index 5: print (numbers [index]) index = index + 1 The goal of this lab is to conrert the blood drive program from Lab 7.1 to Pythan code. Step 1: 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 Lab7-4.pp. B

Explanation / Answer

Note: I have used raw_input. You can use input function for newer versions of python. below is the code:

def main():

endProgram ='no'

pints = [0] * 7

totalPints = 0

averagePints = 0

highPints = 0

lowPints = 0

  

while endProgram == 'no':

pints = getPints(pints)

totalPints = getTotal(pints, totalPints)

averagePints = getAverage(totalPints, averagePints)

highPints = getHigh(pints, highPints)

lowPints = getLow(pints, lowPints)

displayInfo(averagePints, lowPints, highPints)

  

  

endProgram = raw_input('Do you want to End the program? (Enter yes or no): ')

while not (endProgram == 'yes' or endProgram == 'no'):

print 'Please enter a yes or no'

endProgram = raw_input('Do you want to End the program? (Enter yes or no): ')

  

def getPints(pints):

counter = 0

while counter < 7:

pints[counter] = raw_input('Enter pints collected: ')

counter = counter + 1

return pints

  

def getTotal(pints, totalPints):

counter = 0

while counter < 7:

totalPints = totalPints + int(pints[counter])

counter = counter + 1

return totalPints

  

def getAverage(totalPints, averagePints):

averagePints= totalPints/7

return averagePints

def getHigh(pints, highPints):

counter = 1

highPints = pints[0]

while counter < 7:

if pints[counter] > highPints:

highPints = pints[counter]

counter = counter + 1

return highPints

def getLow(pints, lowPints):

counter = 1

lowPints = pints[0]

while counter < 7:

if pints[counter] < lowPints:

lowPints = pints[counter]

counter = counter + 1

return lowPints

  

def displayInfo(averagePints, lowPints, highPints):

print "The average number of pints donated is: " + str(averagePints)

print "The highest number of pints donated is: " + str(highPints)

print "The lowest number of pints donated is: " + str(lowPints)

  

main()
