If you're running this in an interactive interpreter, I would
expect it to show a list of lines (assuming c:/testing.txt has
something in it...). If you're running it as a program, though,
it won't show anything: you need to actually output the result
of the expression f.readlines (). It only happens at the
interpreter as a development convenience:

f = open ("c:/testing.txt", "r")
print f.readlines ()
# or print (f.readlines ()) if you're in Python 3
