EnvManager

Resumen

EnvManager is a class for managing geoprocessing environments.

The environment settings set by the EnvManager class are temporary and are only set for the duration of the with block. At the completion of the with block, the environments passed to the EnvManager class will be reset to their values prior to the EnvManager class (you do not need to reset the environment values yourself).

EnvManager example 1

Use EnvManager to temporarily set the cellSize and extent environments prior to executing the PointDensity tool.

import arcpy
feature_class = r'd:\data\data.gdb\cities'

with arcpy.EnvManager(cellSize=10, extent='-16, 25, 44, 64'):
    raster = arcpy.sa.PointDensity(feature_class, 'POP_RANK')

EnvManager example 2

Use EnvManager to temporarily set the workspace environment prior to accessing the ListFeatureClasses function.

import arcpy

with arcpy.EnvManager(workspace=r'd:\data\data.gdb'):
    feature_classes = arcpy.ListFeatureClasses(feature_type='POLYGON')

print('The polygon feature classes are {}'.format(', '.join(feature_classes)))
