Issues running python scripts in Command Prompt (Specifically with command line arguments)?
I know this is an old thread, but I have searched for a few weeks for this very same problem and found nothing. 
Today, however, I tried something new: 
If you are using Windows 7, do not use Command Prompt for scripting purposes. 
Instead, use the Windows PowerShell located at: All Programs -> Accessories ->  Windows PowerShell -> Windows PowerShell. In there you can run the command django-admin.py startproject mysite if you added the correct paths to your environmental paths. 
BTW, I'm now using Python 2.7 with Django 1.2.4 on Windows 7 Ultimate 32bit.
I am trying to run my python scripts in the command-prompt without calling python.exe first. I am specifically doing this in relation to running django-admin.py. I have C:\Python26 and C:\Python26\Scripts in my PATH. However, if I try running django-admin.py by doing:  

django-admin.py startproject helloworld  

I get the message: Type 'django-admin.py help' for usage.
Now, after some experimentation, I realized the problem is that the secondary arguments to these scripts are not being passed for some reason, since I tried it with a some other python scripts I have. I know I could avoid this problem by simply doing:  

python C:\Python26\Scripts\django-admin.py startproject helloworld  

But I know it should be possible to run the first command only and get it to work, because I had it working before. I've looked everywhere, and not many places have been helpful so any idea would be useful for me at this point. 
Update: The .py file associations were set correctly, and the problem is still occuring.
