Question

I have a text file and I need to read from the seconds line to to 15th line including. I've tried some methods but no method worked for me... I'd be happy if anyone could help me ... thanks a lot!

Was it helpful?

Solution

Use itertools.islice:

from itertools import islice
with open('filename') as fin:
    for line in islice(fin, 1, 16):
        print line

OTHER TIPS

If the file isn't very big:

with open('/path/to/file') as f:
    print f.readlines()[1:15]

Jon's answer is definitely a more pythonic and clean approach.


Alternatively, you can use enumerate():

with open("file", 'r') as f:
    print [x for i, x in enumerate(f) if 1 <= i <= 15]

Note, that this will loop over all lines in a file. It's better to break the loop after the 15th line, like this:

with open("file", 'r') as f:
    for i, x in enumerate(f):
        if 1 <= i <= 15:
            print x
        elif i > 15:
            break

I think you can just read the lines and take the ones you need

For example:

with open("a.txt", "r") as text_file:
    data = text_file.readlines()

now data[1] will be second line and data[14] will be 15th, so you can slice it as such data[1:14]

Then you can put them into a variable and that's it
