These are "key arguments" also called "named arguments". If you are more familiar with other languages, where there are only "positional arguments" this def call would have same effect as your code, ie. you can use named on positioned arguments in python:

  set_action_delays(self, False, None, None, None, None, None, False, None, None, True)

They are default parameter values: https://www.w3schools.com/python/gloss_python_function_default_parameter.asp

For instance, looking at safety_match: bool = True: the default value would be set to True in the case that the function is called without the argument.

The int, bool, etc are type hints: https://mypy.readthedocs.io/en/stable/cheat_sheet_py3.html
