Hello Everyone,
I am to make a small programme for a friend of mine
where i am to start reading from 14th (string) from a file and then
read every 5th row.
ie.
in 1st read it reads the 14 row in a File, write to an OUTPUT-1 file
Next reads 19th row, write to the OUTPUT-1 file
then 24th row,... so on.
and the second loop does is
reads the 15th line as the first line from same input file and write
to OUTPUT-2 file
next reads 20th line / row, write to the OUTPUT-2 file
I have tried various ways but some how i am ONLY able to do i simple
read from one file and write to another.
There are 3024 rows / lines PER file and there are 24 such file I need
to run the programme on.
I really need this on an urgent basis. can some one please help me in this.
Thanks in Advance
Nitin
Write a function that takes a pair of filenames and the starting line #
to begin reading. Then call it in a loop from 14 through 19. And call
that loop for each input file.
The loop inside the function body could be as simple as (untested):
for line in itertools.islice(infile, startnum, 10**6, 5):
outfile.write(line)
