Three options:
Either you run
python C:\path\to\django-admin.py startproject mysite
from whatever directory you want, to run an arbitrary Python script
anywhere on your machine.
Or, with other scripts, from the directory where the Python script is,
you can generally do
python some-script.py C:\path\to\some\target
depending how the script itself is set up -- the django-admin.py
doesn't let you do this, it wants only to create a project in the
current directory.
Or (what you're encouraged to do in this case) the django-admin.py
script is set up somewhere in your lookup PATH. The lookup PATH is the
list of directories in which commands live, and so when asked to run a
particular command the shell looks in those directories and if it
finds the command you wanted runs it, no matter where you are. To get
the django-admin.py script in the PATH so you can run it from anywhere
without a full path either you install the script to a directory which
is already in your PATH (I think on Windows C:\windows\system32 is one
such directory) or the Django directory containing the script is added
to your PATH.
There might have been instructions to do that when you installed
Django, or perhaps it was done as part of an installation script.
The fact that this path exists is the reason you can run commands like
"python" itself from anywhere, if it's set up properly.
