#opening the file with the given name in read mode
read_file=open(input_file_name,'r')

#reading the line into a line variable
line_variable=read_file.readline()

#iterating to the loop untill the end of the page and all lines read
while(line_variable!=""):
  #printing the read line by removing the extra \n as print will display in new line at every time. If you want extra line space you can remove that .strip("\n")
    print(line_variable.strip("\n"))
