13.3Process scores in a text file) Suppose that a text file contains an unspecified nu ber of scores. Write a program that reads the scores from the file and displays their total and average. Scores are separated by blanks. Your program should prompt the user to enter a filename. Here is a sample run: Enter a filename: scores.txt There are 70 scores The total is 800 The average is 33.33

Explanation / Answer

# function to convert list of strings to real numbers
def toNumbers(nums):
   for i in range(len(nums)):
       nums[i] = int(nums[i])

# function to square the numbers in a list
def countNums(nums):
   count = 0
   for i in range(len(nums)):
       count = count + 1
return count

# function to add the numbers in the list
def sumList(nums):
   total = 0
   for i in nums:
       total = total + i
   return total

# program that pulls numbers from file and computes sum of the square of the numbers
def main():
   fname = input("Please enter the name of the file to be opened: ")
   nums = open(fname, 'r')
   strings = ""
  
   #create a string rather than a list with readlines
   #so we can remove extra spaces with the .split() method later

   for line in nums.readlines():
       strings += line

   #make sure to close nums
   nums.close()

   #remove spaces and store this result in the list nums_array
   nums_array = strings.split()

   print("The numbers in this list are:")
   print(nums_array)
  
   # Convert strings in list to actual numbers
   toNumbers(nums_array)
   # Counting total no of elements
   count =countNums(nums_array)
   total = sumList(nums_array)
      avg = total/count
  
   print
      print("The number of elements is: " + str(count))
   print("The sum of the numbers from this list is: " + str(total))
      print("The average of the numbers from this list is: " + str(avg))

main()
