Easily add an empty choice to a Django ChoiceField
from django import forms
class EmptyChoiceField(forms.ChoiceField):
def __init__(self, choices=(), empty_label=None, required=True, widget=None, label=None,
initial=None, help_text=None, *args, **kwargs):
# prepend an empty label if it exists (and field is not required!)
if not required and empty_label is not None:
choices = tuple([(u'', empty_label)] + list(choices))

Easy parallel python with concurrent.futures

Easy parallel python with concurrent.futures

As of version 3.3, python includes the very promising concurrent.futures module, with elegant context managers for running tasks concurrently. Thanks to the simple and consistent interface you can use both threads and processes with minimal effort.

For most CPU bound tasks - anything that is heavy number crunching - you want your program to use all the CPUs in your PC. The simplest way to get a CPU bound task to run in parallel is to use the ProcessPoolExecutor, which will create enough sub-processes to keep all your CPUs busy.

We use the context manager thusly:

with concurrent.futures.ProcessPoolExecutor() as executor:
