One of the most useful trick I found was installing the tool via sitecustomize.py so you don't need the import:

    # add devtools debug to builtins
    try:
        from devtools import debug
    except ImportError:
        pass
    else:
        __builtins__['debug'] = debug

(see https://github.com/samuelcolvin/python-devtools#usage-withou...)

This would work with icecream too.

The second advantage of not needing the import is that CI fails if you forget to remove all debug() commands.
