How clever would you like it? This one is straight from the standard
tutorial, Chapter 7. Say you want to read from a file named "file.txt", and
print each line. Just do:

input=open('file.txt','r')         #open file.txt for reading
while 1:
   newline = input.readline()    #read a line
   if newline == '': break         #is it empty? you've hit eof. stop reading

   print newline                       #else, print the line

I hope it helps.
