In the first week of GIS Programming, we were introduced to the concept of pseudocoding to help us learn how we'll be constructing Python scripts later on. This is a step-by-step script that is more-or-less like English, that puts together the Input, the desired Output, and a list of the tasks necessary to get from the Input to Output. We also examined the interactive window of Python, in which script can be run a line at a time, the Pythonwin script editor, in which multiple lines of script can be compiled, saved, then run. A Python interactive window is also accessible through ArcMap, by clicking the Python Window button on the standard toolbar. This environment is convenient, because when you start typing, it gives suggestion prompts for possible statements from which you can select. Also, there is help and syntax information in this window for whatever statement you select .
