Answer:
In Python:
import os.path
from os import path
fname = input("Filename: ")
if path.exists(fname):
 with open(fname) as file_in:
  lines = []
  for line in file_in:
  	lines.append(line.rstrip('\n'))
 f = open("stat.txt","r+")
 f.truncate(0)
 f = open("stat.txt", "a")
 f.write("Names\tTotal\tSubjects\tAverage\n")
 for i in range(len(lines)):
  rowsum = 0; count = 0
  nm = lines[i].split()
  for j in nm:
  	if (j.isdecimal()):
    count+=1
    rowsum+=int(j)
  average = rowsum/count
  f.write(nm[0]+"\t %3d\t %2d\t\t %.2f\n" % (rowsum, count, average))
 f.close()
else:
 print("File does not exist")

25 SQUARES
How this is calculated?
- The size of the squares doesn't matter, since the number of squares will be the same.
- We have a row of 5 squares: and on top of this you stack 5 more squares.
- Doing this for a total of 5 times so that we  have 5 rows with 5 squares each.
- So we have 5 + 5 + 5 + 5 + 5 = 25 squares.
What is an array?
- An array is a data structure that holds similar, related data.
- Before an array can be used, it must be declared. To declare an array a programmer gives it at least two properties:
- an identifier
- a size - the number of elements it will hold
