If you have read the two previous articles ArcGis and Python: Before your first steps and\n ArcGis and Python: getting started<\/a> , you are\nready to get started. <\/p>\n\n\n\n

There are two things you need to learn: the Python language and how to\nuse the ArcGis Python geoprocessing library. As for Python, tutorials abound. But\ndo not forget that you will only need some basics of the language. You will\nbasically string together already existing ArcGis tools. <\/p>\n\n\n\n\n\n\n\n

Here, we will discuss a first script example and its integration in your\npersonal toolbox. We will, still, use the Clip<\/em><\/strong> tool of a layer. Let’s\nsay we want to adapt the Clip<\/em><\/strong> tool so that it, automatically,\nsplit all layers in a workspace (directory, geodatabase), storing the results\nin another workspace. <\/p>\n\n\n\n

We could make a model with Model Builder using a data input iterator. And\nbesides that’s probably what you would do now if you’re just starting with\nPython. So let’s see how to do the same thing with Python. <\/p>\n\n\n\n

As example we will use PyScripter,<\/em> but in this case, you do not\neven need IDE. A text editor can do the trick. On the other hand be aware that with\nPython, the lines indentation is part of the syntax and that typing a code line\nat the beginning of the line or after one or two tabs does not mean the same\nthing. <\/p>\n\n\n\n

An IDE will automatically position you where it is needed. <\/p>\n\n\n\n

Launch your IDE or open your text editor.
