> Why the one would write functional code in a language that ain’t very good with maps and filters, has no lazy calculations and has no constants on language design level?

Python is fine with maps and filters, and has lazy calculations.

The map() function is already lazy (in python 3 it returns a generator, and not a materialized list).

You can also have a look at "generator expressions", which are the lazy counterpart to a list comprehension (hint: use " ()" instead of "[]").
