Question

Write a program that computes and prints the average of the numbers in a text file. You should make use of two higher-order functions to simplify the design.
An example of the program input and output is shown below:




Enter the input file name: numbers.txt




The average is 69.83333333333333



______________________________________




Filename: numbers.txt




45 66 88



100 22 98

Answer 1

Answer:

Following is the program code as required.

Comments are given inside the code.

Explanation:

(=> Defining the main function)

def main():

(=> Getting input from user)

file = input("What is name of file?")

(=>Storing text from file in variable data )

data = open(file, "r")

(=> read the file and then split it)

info = data.read().split()

(=> Generating array named numbers)

numbers = []

for line in info:

(=>numbers will be appended from in format to list format)

numbers.append(int(line))

data.close()

(=> Average will be found by dividing sum of numbers to length of array)

avg = float(sum(numbers))/len(numbers)

(=> Printing calculation of average)

print("Calculated average is",avg)

main()

i hope it will help you!
