Summary
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 revert to their previous values (you do not need to manually reset the environment values). The code indented under the with statement can include a single line of code or multiple lines.

Code sample
Use EnvManager to temporarily set the cellSize and extent environments before to running the PointDensity function.
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')
Use EnvManager to temporarily set the workspace environment before 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)))
