    Django 1.10.3 adds important change in settings

    The latest Django update, version 1.10.3 adds an important change to how Django handles the ALLOWED_HOSTS setting in your project. Previously, when running in debug mode (with DEBUG=True setting) Django ignored the ALLOWED_HOSTS setting, accepting any hostname. Since the latest update Django will validate the values in this setting regardless of the DEBUG  setting. For convenience, if ALLOWED_HOSTS is empty and DEBUG=True, the following variations of localhost are allowed [‘localhost’, ‘127.0.0.1’, ‘::1’]. This change might present an issue for you if you are running a QA version of your project with the DEBUG setting or if you’re developing using production settings in the ALLOWED_HOSTS setting.

Return [crayon-5bcc61e56e540209376876-i/]  from your callable to perform a…

Everyone knows how to create a tuple, right? [crayon-5bcc61e56eb3b043186870/] Well using tuple unpacking, you can get all values from a tuple in one expression and store them in their own variables. [crayon-5bcc61e56eb3f178660889/] This allows you to do fun stuff like return multiple values from a function, by returning them as a tuple. After getting the return value from a function you simply unpack the tuple. [crayon-5bcc61e56eb40736562527/] And unpacking the returned tuple in one simple expression: [crayon-5bcc61e56eb42013439478/]
