Run python script inside another python script

I have a script 'preprocessing.py' containing the function for text preprocessing:

def preprocess():
    #...some code here
    with open('stopwords.txt') as sw:
        for line in sw.readlines():
            stop_words.add(something)
    #...some more code than doesn't matter
    return stop_words

Now I want to use this function in another Python script. So, I do the following:

import sys
sys.path.insert(0, '/path/to/first/script')

from preprocessing import preprocess
x = preprocess(my_text)

Finally, I end up with the issue:

IOError: [Errno 2] No such file or directory: 'stopwords.txt'

The problem is surely that the 'stopwords.txt' file is located next to the first script, not the second.

Is there any way to specify the path to this file, not making any changes to the script 'preprocessing.py'?

Thank you.

Since you're running on a *nix like system, it seems, why not use that marvellous environment to glue your stuff together?

cat stopwords.txt | python preprocess.py | python process.py

Of course, your scripts should just use the standard input, and produce just standard output. See! Remove code and get functionality for free!

import os
def preprocess():
    #...some code here
    # get path in same dir
    path = os.path.splitext(__file__)
    # join them with file name
    file_id = os.path.join(path, "stopwords.txt")

    with open(file_id) as sw:
        for line in sw.readlines():
            stop_words.add(something)
    #...some more code than doesn't matter
    return stop_words

Looks like you can put

import os
os.chdir('path/to/first/script')

in your second script. Please try.

The simplest, and possibly most sensible way is to pass in the fully pathed filename:

def preprocess(filename):
    #...some code here
    with open(filename) as sw:
        for line in sw.readlines():
            stop_words.add(something)
    #...some more code than doesn't matter
    return stop_words

Then you can call it appropriately.
