Right-click the code in the transcript of the Python window and click Save Transcript. You can save your code from the Python window to a Python script file to start your work in a Python editor. #Difference between transcad and arcgis pro#
You can also use the code outside of ArcGIS Pro in a Python editor, which you will do next. Those steps are not covered here, but you can copy the code from the Python window and paste it into a cell in Notebooks. The same code used in the Python window can also be used in an ArcGIS Notebooks in ArcGIS Pro (or in a Jupyter Notebook, outside of ArcGIS Pro). You can add code to create a more meaningful output, such as including the feature class name after each count, writing the results to a text file, calculating a total number of features in the workspace, or determining the feature class or classes with the most features. The code is not very polished, since for many shapefiles it would be cumbersome to read the printout. The code you have developed accomplishes the task of counting the features in each shapefile. The result prints the number of features for each of the shapefiles in the workspaces. In addition to the workspace, environments include the default output coordinate system, the default cell size for raster data processing, and several others. A workspace is one of several environment settings that influence geoprocessing operations.

Instead of specifying the full path, you can set the workspace. Using only ambulances would return an error since there is no feature class named ambulances in the folder. Third, the feature class is referenced as ambulances.shp since the. This can result in unintended consequences when you use backslashes in strings. A backslash in Python is used as an escape character, which may change the meaning of the character following it. Also note that a forward slash (/) is used in the path instead of a regular backslash (\). Second, the path is in quotation marks because it is a string. First, if you extracted the data to a different folder, you will need to modify this path. There are some points to note about the use of the path.

If you saved the PythonStart folder to another location on your computer, you will need to update the path accordingly.
Click the end of the line of code and press Enter. For example, print(“GIS is cool”) results in an error. Sometimes, if you copy code that has been formatted or written in word processing software, the straight quotation marks may be replaced by slanted quotation marks. They are automatically formatted this way when you type your code in the Python window or another coding environment. Quotation marks in Python are always straight (as opposed to slanted). Both print("GIS is cool") and print('GIS is cool') are therefore correct, but print("GIS is cool') results in an error. Python uses both single and double quotation marks to identify strings, provided they are used consistently. You create a string by enclosing the characters in a pair of quotation marks. A string in Python consists of a sequence of characters. Most functions in Python have arguments or parameters, which are provided in parentheses following the function. A function in Python carries out a specific task. Specify the name and location for the output raster.In this line of code, print() is a function. In the Raster Calculator window, double-click one of the rasters to be analysed, click the minus sign ( -), and double-click the second raster. In ArcMap, navigate to ArcToolbox > Spatial Analyst Tools > Map Algebra > Raster Calculator. Option C describes the steps to find the raster value differences using the Difference tool from the Image Analysis window, which does not require an extension. Option A describes the workflow when using the Raster Calculator tool from the Map Algebra toolset, whereas Option B describes the workflow when using the Minus tool from the Math toolset. The instructions provided describe the steps to find raster value differences between two rasters. The Raster Calculator and Minus tools require a Spatial Analyst license. Alternatively, environments without the ArcGIS Spatial Analyst extension can use the Difference function from the Image Analysis window. In ArcGIS Desktop, these tools are located in the Spatial Analyst toolbox. Spatial analysis tools such as the Raster Calculator and Minus tools can provide powerful insights on raster value differences between raster images that are geographically overlapping.
