[Tutor] A Really Quick Question

Folks,
I am running Python 2.1 which ships with ArcView 9.1. I am going through
the 2.1 tutorial and came across readlines(). Simply put it doesn't seem to
be behaving as the tutorial describes. Specifically, I created a small text
file as shown below:
f=open("c:/python21/sfh_modules/test.txt", "w")
f.write("This is the second line\n")
f.write("This is the second line\n")
f.close() # then closed and reopened in read mode
f=open("c:/python21/sfh_modules/test.txt", "r")
f.readlines(2) # Here's my problem
['This is the first line\n', 'This is the second line\n'] # please note
this output
The tutorial seems to be telling me that 'f.readlines(2) should read out 2
bytes plus what is needed to complete the current line. Instead, it is
reading out the entire file no matter what I enter as a parameter. I know I
am going to feel really dumb when I hear the explanation but please remember
I'm new to this.
Thanks very much,
Steve
