Q: Django - how to return data from other function on views.py

Question

I'm kind of working on string operation, here is what i want to do
- i created a functions gettext(request) for getting text from *.txt files, this is the code

def gettext(request):
  if request.method == 'POST':
    form = UploadFileForm(request.POST, request.FILES)
    if form.is_valid():
        f = request.FILES['file']
        for chunk in f.chunks():
            text = chunk

        return render(request, 'ecs/index.html', {'text': text, 'form': form})      
    else:
        form = UploadFileForm()
return render_to_response('ecs/index.html', {'form': form})

and then i want to get the data that i stored on text variable to a functions, called preprocessing

def preprocessing(text):
    pp = Preprocess()

    wordTokenize = pp.tokenizing(text)

    return wordTokenize

how can i use the preprocessing(text) method to handle data from text variable on gettext method.
i tried some tricks, but still no progress.

import the preprocessing function from wherever you have it into the file that has gettext in it, and then do this:

def gettext(request):
  if request.method == 'POST':
    form = UploadFileForm(request.POST, request.FILES)
    if form.is_valid():
        f = request.FILES['file']
        for chunk in f.chunks():
            text = chunk
            text = preprocessing(text)
        return render(request, 'ecs/index.html', {'text': text, 'form': form})      
    else:
        form = UploadFileForm()
return render_to_response('ecs/index.html', {'form': form})

still not working sir, when i run your code, the output was global name 'request' is not defined so i changed preprocess(text) to preprocess(request, text) and modify text = preprocessing(text) to preprocessing(request, text) and run well, thanks @IsaacRay
