This setting determines the geometry type (such as point or polygon) of the output feature class.
The default is "Img", which is ERDAS IMAGINE format. A workspace is a container for datasets (features, tables, and rasters).
There’s a good chance that you already have Python on your operating system.
If so, you do not need to install or configure anything else to use Python.
Having said that, I would strongly recommend that you install the tools and libraries described in the guides below before you start building Python applications for real-world use.
In particular, you should always install Setuptools, Pip, and Virtualenv — they make it much easier for you to use other third-party Python libraries.
Any time there is an update, this will give us the new graph. Think of it a lot like FPS (frames per second) in things like games.
The updates are fixed, but you can do many updates a second, or just do one update every 5 seconds...
The schema object is created for you by geoprocessing.
You access this schema through the parameter object and set the rules for describing the output of your tool.
If your tool adds datasets to a new or existing workspace, you can update the description of the workspace by adding descriptions of the children.
For example, you may have a tool that takes a list of feature classes (a multivalue), modifies them in some way, then writes the modified feature classes to an existing workspace.
Luckily for us, the creator of Matplotlib has even created something to help us do just that. This video and the subsequent video shows you the animation function, how it works, and gives an example.
