I like to point out Airflow as an example. It's still a complete nightmare to deal with and it has many steps for just packaging the application.

https://github.com/apache/airflow

I have less trouble packaging and running a 3 year unmaintained Maven Java application, than actively maintained Airflow. And let's not forget that I can target Java 8, without having to install Java 8 on my machine. (Which only adds to Python's complexity)
