QUESTION
I am trying to diagnose some shenanigans, where my python code (Lightning.py) executes in a terminal window with "sudo ./Lightning.py" but not withing my cron job.
I am rather new to linux and would welcome any assistance!
Here is the code for Lightning.py
...ANSWER
Answered 2019-Nov-24 at 19:09I think the working directory is not /home/user/Desktop/ when the code runs in cron. Add a line at the beginning of the code:
os.chdir("/home/user/Desktop/")

Install postpy
You can use postpy like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
