Missing exercise data for Visualizing Data Using ArcGIS API for Python

marciehogan

Hello, I am working my way through the Visualizing Data Using ArcGIS API for Python course, and downloaded the required sample data. I am watching the first video in which a shapefile for Liberia airports is mentioned, however I do not see that in the folder I downloaded. I am working with the python notebooks built in to ArcGIS Pro and got the error below when I tried to run the code. I am just starting out with using the ArcGIS pro api and I am not exactly sure what the error means. Thank you in advance for any help!

 

sedf = pd.DataFrame.spatial.from_featureclass('[the rest of my file path]\VisualPythonAPI\Liberia_Airports.shp')

---------------------------------------------------------------------------
SyntaxError                               Traceback (most recent call last)

Hi @marciehogan 

The error is because you are using \ in your filepath. This is a special escape character in Python. You either need to place r in front of your filepath outside the string quotation, use double \\, or use single / as shown below. 

 

r'the\rest\of\my\filepath\VisualPythonAPI\Liberia_Airports.shp'

'the\\rest\\of\\my\\filepath\\VisualPythonAPI\\Liberia_Airports.shp'

'the/rest/of/my/filepath/VisualPythonAPI/Liberia_Airports.shp'

 

See more on Python escape characters here.

While this wont solve a missing Shapefile, it will overcome the SyntaxError you have described above.
