Django Indentation error

Question

I am new to Django and was trying this code in a tutorial. But now I'm not able to run my program because of the following error:

IndentationError at /
('unexpected indent', ('D:\\django_workspace\\django_bookmarks\\..\\django_bookmarks\\bookmarks\\views.py', 14, 4, '    return HttpResponse(output)\n'))
Request Method: GET
Request URL:    http://localhost:8000/
Exception Type: IndentationError

Server time:    Tue, 9 Mar 2010 19:18:32 +

My views.py file code is:

from django.http import HttpResponse, Http404
from django.contrib.auth.models import User
from django.template import Context
from django.template.loader import get_template

def main_page(request):
    template = get_template('main_page.html')
    variables = Context({
        'head_title': 'Django Bookmarks',
        'page_title': 'Welcome to Django Bookmarks',
        'page_body': 'Where you can store and share bookmarks!'
})
output = template.render(variables)
    return HttpResponse(output)

def user_page(request, username):
    try:
        user = User.objects.get(username=username)
    except:
        raise Http404('Requested user not found.')
        bookmarks = user.bookmark_set.all()
        template = get_template('user_page.html')
        variables = Context({
                'username': username,
                'bookmarks': bookmarks
})
output = template.render(variables)
    return HttpResponse(output)

Kindly help me rectify this problem! Thanks in advance.

Solution

Most likely you're mixing tabs with spaces - use one or the other for your indenting... preferably spaces, according to this:

Just gotta love the way significant whitespace makes Python programs "more readable" ;-)
