import arcpy

# Set workspace
arcpy.env.workspace = "c:/data/airport.gdb"

# Set local variables
in_features = arcpy.GetParameterAsText(0)
clip_features = arcpy.GetParameterAsText(1)
out_feature_class = arcpy.GetParameterAsText(2)
xy_tolerance = arcpy.GetParameterAsText(3)

# Check for required number of arguments
if arcpy.GetArgumentCount() < 3:
    print("3 arguments required for Clip_analysis tool")

# Execute Clip tool
try:
    arcpy.Clip_analysis(in_features, clip_features,
                        out_feature_class, xy_tolerance)
except arcpy.ExecuteError:
    print(arcpy.GetMessages(2))
GetArgumentCode example 2
