Question

in PYTHON

If varible counter contains an integer, then write an augmented assignment operation to decrement it by 1. A “count-controlled” for loop using the xrange function to average the scores for a class is given below and in the file PartD_average_with_for.py:

# Calculates the average score using a counter-controlled for-loop numberOfScores = input("Enter the number of scores to average: ")

total = 0.0;

for counter in xrange(numberOfScores):

score = input("Enter score #" + str(counter+1) + ": ") total = total + score

if numberOfScores > 0:

print "The average score is", total / numberOfScores

Answer 1

Code:

#Define count

numberOfScores=input("Enter count of scores:")

#Define total

total = 0.0;

#Loop until count of scores

for counter in xrange(numberOfScores):

    #Get value of score

    score = input("Enter score #" + str(counter+1) + ": ")

    #Update score

    total = total + score

    #Decrement counter

    counter = counter-1

#If count greater than 0

if numberOfScores > 0:

    #Display result

    print "The average score is", total / numberOfScores

#Receive number of days

days = int(input("Number of days"))

#Set amount as 1

amount = 1

#Loop until days count

for lcounter in range(days):

    #Double amount each day

    amount = amount*2

#Display total salary paid

print"Total salary paid is "

print amount

print "pennies"
