actual commands

I would like to delete those two lines at the very beginning of the
file between two comment blocks. I have read things about python but my
library knowledge is still weak. So could you please help me with this
code.

I would like to call this as

myscript targetfile

that myself but help is also appreciated on that.

Best regards,
