How can I execute a python script directly (without prefix by the python command) from bash?

I am just starting to use the terminal for my programming needs. In many Django tutorials, I see people say, for example, that I have to type this in the terminal:

manage.py runserver

However, when I do this, he says:

bash: manage.py: command not found

I make it work when I do: python manage.py runserverhowever I would like to understand why this works and the other does not. I think these are some very simple things, but I thought I would ask here.

"script", : ( .)

tee -a ~/.profile <<EOF

if [ -d "/Library/Python/2.6/site-packages/django/bin" ] ; then
    PATH=/Library/Python/2.6/site-packages/django/bin:$PATH

django-admin.py ? , manage.py ../bin. , . ;)

Also, did you get Django through easy_install? My script expects you to use Snow Leopard with the system version (Python 2.6).
