Assume that a file containing a series of integers is named numbers.txt. Write a program that calculates the average of all the
Anna [14]

Answer:

Program in Python:

file = open("numbers.txt", "r")

count = 0

isum = 0

content = file.readlines()

for nums in content:

    num = nums.rstrip('\n').split(" ")

         for i in num:

              isum= isum + int(i)

              count = count + 1

print("Average: "+str(isum/count))

Explanation:

This line opens the file named numbers.txt

file = open("numbers.txt", "r")

This line initializes num to 0

count = 0

This line initializes sum to 0

isum = 0

This line reads the content of the opened file file

content = file.readlines()

This iterates through the content of the file

for nums in content:

This removes trailing new lines and blank spaces from each number

    num = nums.rstrip('\n').split(" ")

This also iterates through the content of the file

         for i in num:

This calculates the sum of the numbers in the file

              isum= isum + int(i)

This counts the numbers in the file

              count = count + 1

This calculates and prints the average of the numbers

print("Average: "+str(isum/count))
