title: django-admin startproject gives SyntaxError
body: <p>I tried to start a new project with django 4.0 After installing Django in environment folder (Anaconda/envs/taskman) I created a new folder somewhere in my e: drive and by using windows command line created a new folder Django_site. Then from this folder I typed in command line prompt: django-admin startproject lifetool and got the following:</p>
  <pre><code>    (taskman) E:\Projects\Django_site&gt;django-admin startproject lifetool
