as Fredrik told you, you can not delete the first line directly!!!

We are trying to understand that, but it is expected some effort on
your side as well :)
You didn't read the documentation properly!
try to experiment with the code by yourself as well!
Try:
1) open your file
2) use readlines() method
which returns the list of ALL rows from the file and store them to some
variable.
it can be done for example like:
all_lines = f.readlines()
(if you do not know, what the list is, start here:
http://docs.python.org/tut/node5.html#SECTION005140000000000000000)
4) save the list members without its first member to the file
for example:
for line in all_lines[1:]:
f.write(line)
5) close the file
Good luck
