Hi,
Go easy on me as I am a new to Python and am trying to solve a practical
problem that is driving me bananas.
Basically I have 2 text files, a source and a target. I want to be able to
delete all of the lines in the target file which contain text from any line
in the source file.
i.e.

I am new in python and I have the following problem:
Suppose I have a list with words of which I want to remove each time
the words in the lines below item1 and above item2:
item1
a
b
item2

d
item3
e
f
item4
g
h
item1

j
item2

As I said I am no expert in OS and commands, except on what concerns mechanical
statistical and quantum mechanical calculations. Therefore, better for me (and
for all guys here) if I stop on this matter. My reply is only to say that I did
the job with:
f=open("prod1-3_no_wat_pop.pdb", "r")

f=open("output.pdb", "r")
for line in f:
