![]() ![]() A string in Python consists of a sequence of characters. ![]() You create a string by enclosing the characters in a pair of quotation marks. Python uses both single and double quotation marks to identify strings, provided they are used consistently. Both print("GIS is cool") and print('GIS is cool') are therefore correct, but print("GIS is cool') results in an error. Quotation marks in Python are always straight (as opposed to slanted). They are automatically formatted this way when you type your code in the Python window or another coding environment. 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. Click the end of the line of code and press Enter.For example, print(“GIS is cool”) results in an error. If you saved the PythonStart folder to another location on your computer, you will need to update the path accordingly. There are some points to note about the use of the path. First, if you extracted the data to a different folder, you will need to modify this path. Second, the path is in quotation marks because it is a string. Also note that a forward slash (/) is used in the path instead of a regular backslash (\). A backslash in Python is used as an escape character, which may change the meaning of the character following it. This can result in unintended consequences when you use backslashes in strings. Third, the feature class is referenced as ambulances.shp since the. Using only ambulances would return an error since there is no feature class named ambulances in the folder. Instead of specifying the full path, you can set the workspace. In addition to the workspace, environments include the default output coordinate system, the default cell size for raster data processing, and several others.Ī workspace is one of several environment settings that influence geoprocessing operations. The result prints the number of features for each of the shapefiles in the workspaces. ![]()
