Crontab script running from sh-3.2 (logged in as root) is:

* * * * * python /Users/tony/Documents/Python_Projects/Stock_Earnings_5.py #send an email every minute

Stock_Earnings_5 sends an email based on the logic.

Currently Stock_Earnings_5 works independently and sends out the email when manually running it from shell sh-3.2 (logged in as root).

crontab also works for "hello world" to terminal.

So in summary, crontab works for hello world program to terminal, and Stock_Earnings_5 works if called independently of crontab, but when crontab calls Stock_Earnings_5 it doesn't send email.

To properly post my comment above:

Keep in mind that the environment in which cron runs has different (minimal) variables that your user environment. Therefore, it might be (and usually is) necessary to provide the explicit path to your python executable.

The path to your default python executable can be found using the which python command.

Example:

$ which python
/home/username/anaconda3/bin/python

Then, in cron use:

* * * * * /home/username/anaconda3/bin/python /full/path/to/myscript.py
