Accredited by the Association for Geographic Information (AGI) for 1 CPD point.
User Input
Just the one. The path to the feature class or table.
## the path to the feature class to get the feature count
fc_path = r"C:\path\to\fc_or_table"
The GetCount Geoprocessing Tool
We use the GetCount() geoprocessing tool from the Data Management Toolbox
feature_count = arcpy.management.GetCount(
in_rows = fc_path
)
Print and Assess
Geoprocessing tools in ArcPy return a Result object that contains the output(s) from the tool. It is good to have knowledge about the Result object and accessing the output generated such as the count of features in a Feature Class from the GetCount tool.
print(feature_count)
#print(int(feature_count)) ## this will fail (TypeError) cannot cast Result to int
print(feature_count[0])
print(type(feature_count[0])) # number is a string
print(int(feature_count[0])) # cast to integer
print(type(feature_count)) # Result object returned from geoproccessing tool.
print(feature_count.outputCount) # GetCount returns one output
print(feature_count.getOutput(0)) # access the output via the Result object
