How to interpret python code in Django when trying to open files?

I have below codes written in python in Django. Since I am new to Django and python, I have a hard time understanding below code. What makes me understand hard is that the function process(f) inside in the for-loop. why does it have to be inside the for-loop? 

def Upload(request):
    for count,x in enumerate(request.FILES.getlist("files")):
        def process(f):
            with open('/Users/sclee/PycharmProjects/uploadFile/bin/upload/media/file_' + str(count),'wb+') as destination:
                for chunk in f.chunks():
                    destination.write(chunk)
        process(x)
    return HttpResponse("File(s) uploaded")

No, you don't have to. You can put it anywhere, even outside of the python file in which you are uploading files. Lets say, you have it handle_upload.py file, in which you have written process function to handle uploads. Then you can use it like this:

# in handle_upload.py

def process(f, count):
        with open('/Users/sclee/PycharmProjects/uploadFile/bin/upload/media/file_' + str(count)+'.txt','wb+') as destination:
            for chunk in f.chunks():
                destination.write(chunk)


# inside views.py

from .handle_upload import process  # assuming handle_upload.py is in same directroy as this view file

def Upload(request):  # use snake_case for defining functions. Please read PEP-8 Style guide
    for count,x in enumerate(request.FILES.getlist("files")):
        process(x, count)
    return HttpResponse("File(s) uploaded")
