can %s be an integer? *Python code*
python
Solution
`%s` calls the `str()` method on its corresponding argument... (similar to `%r` calls `repr()`) - so either of those can be used for any object... Unlike `%d` (`%i` is the same) and `%f` for instance which will require appropriate types.
Problem
Looking at this django code from the djangobook: ``` from django.http import Http404, HttpResponse import datetime def hours_ahead(request, offset): try: offset = int(offset) except ValueError: raise Http404() dt = datetime.datetime.now() + datetime.timedelta(hours=offset) html = "<html><body>In %s hour(s), it will be %s.</body></html>" % (offset, dt) return HttpResponse(html) ``` after the try, it converts offset into an integer, right? and in the line 'datetime.timedelta(hours=offset)', offset is used as an integer, but in the line 'html = "In %s hour(s), it will be %s." % (offset, dt)' offset is a %s which is a string, right? Or am I miss understanding? I thought %s only can be a string, not an integer?
