'''
 This program does this:
 opens a file,
 finds the biggest number in it
 prints the max
'''

file_name = 'numbers.txt'
handle = open(file_name, 'r')
lines = handle.readlines()
numbers = []
for line in lines:
    fields = line.split()
    for field in fields:
        number = int(field)
        numbers.append(number)

  At this point in the program, the list "numbers" has all
  all the values in the file

        biggest = number
