How can I import a geodatabase into a python script as a parameter?

[TiffanyRoberts2]

I have the script to list all feature datasets, feature classes and field properties within a geodatabase, but I would like to make the input gdb a parameter(argument). I am more familiar with model builder, but python seems more favorable of a code for this circumstance. I would like the output to simply be through IDLE, I just want to make the gdb a variable.

new to python script,but working at it, any advice is appreciated!

it is a workspace ListWorkspaces—Help | ArcGIS for Desktop

So you can use it to list file geodatabases within a folder for instance, just select the limiter that you wish to show

If you create you own script tool and set it up to accept parameters, you should be able to load the custom Python module/tool and run it at the command prompt.
