cron not executing python3
I am running Raspbian Stretch and have a python 3 script that executes correctly when I am in the relevant directory and input it in the command line as:
sudo python3 Example.py
The shebang #! line is in the script as follows:
#!/usr/bin/env python3
And made the script executable with:
sudo chmod +x Example.py
I've tried several variation of below within crontab -e to no avail
10 * * * * python3 /home/pi/Desktop/Example.py

As is typical with crontab issues. The environment is not the same as your user or even a sudo/root shell , and env python3 may not return anything (env simply searches through
Instead you should explicitly use the full path of python which can be found either as which python3 or which $(env python3) and use that full path in your cronttab (typically /usr/bin/python3 but it is also valid to use one installed elsewhere , e.g. a virtualenv directory)

Try the following in crontab:
sudo python3 /home/pi/Example.py
You need the full path to Example.py
You don't really need the shebang.
Or sudo crontab -e for the root crontab with:
python3 /home/pi/Example.py
