Hi,

Sorry, the above output is not complete, please see the following output:
----------------------------------------------------------------------------
# which python3
/usr/local/bin/python3
# ./in.py
-bash: ./in.py: /usr/bin/python3: bad interpreter: No such file or directory
----------------------------------------------------------------------------

Thanks,
