many thanks for insight on coroutine and passing values to generator function!)

which led to dictionary of transform functions:

many thanks for the insight on singledispatchmethod!)
inspired by this solution - used it without annotations - but as decorator with parameter:

thank you for the solution - clear and efficient!)
don't you know why no-one seems to use re.Scanner for this mission?
it is from Python Cookbook, looks very convenient - for example:

initial version:

which led to more compact:

with lambda transcode dictionaries)

very interesting solution, thank you!)

very interesting regex substitution to add thousand space delimiter:
re.sub(r"\B(?=(?:\d{3})+$)", " ", str(salary * working_years * 12))
\B - not at the beginning of the string
(?:\d{3}) - non-capturing group of 3 digits
(?:\d{3})+ - one or more of such groups
(?:\d

thanks a lot for ... Ellipsis!

very interesting)

interesting solution, thank you!
i suppose, you could use:
datetime.max
for
END = datetime(9999, 12, 31, 23, 59, 59)
)

which led to more creative solution:
- lambda dictionary
- dict merge
- exhaustive pairwise sum
- antidiagonal flip)

interesting usage of hash, thank you)
does it have any advantages over usual comparison?
