Question

I have a Django view which reads a CSV file and saves it to a model.

views.py:

def csv_upload(request):
    ...
    file = request.FILES['attach']
    reader = csv.reader(file, delimiter=';') 
    next(reader) # skip headers

    for line in reader:
        ... # process and save

EDIT

Traceback:

File "/home/sam/django-projects/datazone/local/lib/python2.7/site-packages/django/core/handlers/base.py" in get_response
111.                         response = callback(request, *callback_args, **callback_kwargs)
File "/home/sam/django-projects/datazone/bin/datazone/climate/views.py" in climate_upload
258.                 report.year = line[1]

Exception Type: IndexError at /climate/upload/
Exception Value: list index out of range

END EDIT

Whilst testing with file variations, I noticed that if there is trailing whitespace in the file (e.g. empty rows due to saving form Excel) I get an Index out of range error.

My question is, how can I strip the whitespace from the end (and probably the begining just to be sure) of the file.

Any help much appreciated.

Answer 1

if my understanding is correct, you want to take care of some blank lines in the end of the file, right?

for line in reader:
    if line:
        ... # process and save

Thanks @dm03514 for pointing out a mistake in my original answer
