I'm currently trying to extract some data between 2 lines of an input file
Your subject line says "from word". I'm only guessing that you might
mean Microsoft Word, a proprietary program that does not, by default,
save text files. The following code and description assumes a text
file, so there's a contradiction.
using Python. the infile is set up such that there is a line -START- where I
need the next 10 lines of code if and only if the -END- condition occurs before
the next -START-. The -START- line occurs many times before the -END-. Heres a
general example of what I mean:
In other words, you want to scan for -END-, then go backwards to -START-
and use the first ten of the lines between? Try coding it that way, and
perhaps it'll be easier.
You also need to consider (and specify behavior for) the possibility
that start and end are less than 10 lines apart.
blah

-START-
10 lines I DONT need
blah
-START-
10 lines I need
blah
blah
-END-
blah
blah
-START-
10 lines I dont need
blah
-START-
.... and so on and so forth
so far I have only been able to get the -START- + 10 lines for every iteration,
but am at a total loss when it comes to specifying the condition to only write
if the -END- condition comes before another -START- condition. I'm a bit of a
newb, so any help will be greatly appreciated.
heres the code I have for printing the -START- + 10 lines:
in = open('input.log')
out = open('output.txt', 'a')
lines = in.readlines()
for i, line in enumerate(lines):
if (line.find('START')) > -1:
out.write(line)
out.write(lines[i + 1])
out.write(lines[i + 2])
out.write(lines[i + 3])
out.write(lines[i + 4])
out.write(lines[i + 5])
out.write(lines[i + 6])
out.write(lines[i + 7])
out.write(lines[i + 8])
out.write(lines[i + 9])
out.write(lines[i + 10])
or just out.write(lines[i:i+11) to write out all 11 of them.
