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

JH> in the entry of my posting i wrote, that i am a newbie and so please

JH> understand me, that i ask so questions?! :-)

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
