Assume that a file containing a series of integers is named numbers.dat and exists on the computer's disk. Design a program that displays all of the numbers in the file.

Answer 1

'''
Python version : 3.6
Python program to create a function for displaying the integers
read from file
Each line of the file contains an integer
'''

def printNumberFromFile():
  
   file = open("numbers.dat") # open the file in read mode
   contents = file.readlines() # read the contents of the file into the list with each line being an element of the list
  
   # loop over the contents list
   for line in contents:
       print(int(line)) # print each number by converting it to integer
   #close the file
   file.close()
# call the function
printNumberFromFile()  
#end of program
