Question

write a python program that reads from a file, scores.txt, a list of test scores. the program should calculate the average of all the scores, and print to the screen. the program should also have a function, num_passing, that takes as a parameter the list or grades and returns the number of scores that are above 64.

Answer 1

CODE:

def find_average(filename): //function to find the average of numbers
my_file = open(filename, 'r') //open file in read mode
scores = [float(line) for line in my_file.readlines()] //loading all lines in to a list named scores
my_file.close() //close the open file
mean = sum(scores)/len(scores) //calculate the mean of all scores
print(mean) //print mean
return scores //return scores
  
  
def num_passing(numbers): //function for counting numbers greater than 64
count = len([i for i in numbers if i > 64]) //counts the numbers that are greater than 64
return(count) //return count
  
  
  
def main():   
numbers=find_average('scores.txt') //call find_average function and store the list in numbers
print(num_passing(numbers)) //print count
  

main()

OUTPUT:

First line(55.0) is the average value

second line(4) is the count

sample text file i took
