[Synapse - Apache Spark definition] - Python sample to copy local files to wabs

Hi, It would be nice to have a sample code to copy files from local directories to wabs.

I am developing a Python script in a Spark definition and I would like to copy a local file already created in the temp directory to wasb.

I am trying to use mssparkutils (Maybe this is my error):

local_file = '/tmp/a.txt'
azure_file = 'wasbs://<container>@<storage_account>.blob.core.windows.net/outputs/a.txt'
from notebookutils import mssparkutils
mssparkutils.fs.cp(local_file, azure_file, True)

But, I get error:

Current content of Temp folder:
   /tmp/eea_discodata_task-9c3df798c1ff11ebaedc000d3ab6dc78.log.json
   /tmp/ca-certificates.tmp.3cqtU8

I see that dbutils package is not available in this context, it is used in Databricks environments. Thanks in advance
