Help with templates

THIS IS THE ERROR I ENCOUNTER WHEN I IMPORT DJANGO IN MY SHELL AND TRY TO USE TEMPLATES THERE

 from django import template
>>> t=template.Template('My name is {{ name }}.')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "django/template/base.py", line 123, in __init__
    if settings.TEMPLATE_DEBUG and origin is None:
  File "django/conf/__init__.py", line 53, in __getattr__
    self._setup(name)
  File "django/conf/__init__.py", line 46, in _setup
    % (desc, ENVIRONMENT_VARIABLE))
django.core.exceptions.ImproperlyConfigured: Requested setting TEMPLATE_DEBUG, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.
