1) If possible, don't run shell scripts with Python. Evaluate why you are trying to do that and don't. 2) Python has a bunch of infrastructure compared to shell, you can use it. Shell scripts don't. 3) Apply the same you used for the script to what it calls. CI calls control script for job, script calls tools/libraries for heavy lifting. Often the shell script just calls a python/Ruby/rust exec anyways... Shell scripts are for scripting...the shell. Nothing else.
