ArcPy: check in and out of Advanced/Standard concurrent license

Question

Is it possible to check in and out of a concurrent license straight from ArcPy. For example, sometimes I need to use a buffer right or find duplicates. Both tools require ArcPy advanced or Standard. Although we have a large amount of Basic licenses, we have a small amount of concurrent standard/advanced licenses.

Is it possible to do the following (Pseudo code):

# ...

# Pseudo code:
if license == 'BASIC':
   check_in('STANDARD')
   func_that_does_buff_right(data)
   check_out('STANDARD')
   check_in('BASIC')

Answer 1

Just tried this:

import arcview
import arcpy

print(arcpy.ProductInfo())

import arcinfo

print(arcpy.ProductInfo())

This was the output:

ArcView
ArcView

Not sure if this is the correct approach but looks arcpy didn't change it after trying to import a higher level no error though.

Edit: As per the comments it seems this task cannot be completed within the same session as shown in the OP's pseudo code. That is to say once a license level has been imported it will persist throughout the session regardless of whether a new/higher level license import statement has been executed. There may be a workaround such as creating a separate script to handle higher level geoprocessing ect.
