Why doesn't Cron Ubuntu work?

Question

linux

Trying to run a python script from Cron Ubuntu:
*/10 * * * * /usr/bin/python3 /home/test/test.py
The following is in the logs:
Jun 21 09:59:06 test CRON[8859]: (CRON) info (No MTA installed, discarding output)
Jun 21 10:00:01 test CRON[8971]: (root) CMD (/usr/bin/python3 /home/test/test.py)
But the file itself is not executed, what can be the reason?

Answer 1

CRON) info (No MTA installed, discarding output)
set the thread to MTA, the log of the script will come to the soap
Well, or just redirect the script output to a file
