In Python textbooks that I have read, it is usually not mentioned that

def f1():
n = 0
def f2():
nonlocal n
n += 1
return n
return f2

i. e. we can have several functions with private local states which
are kept between function calls, in other words we can have Common
LISP-like closures.
Out of curiosity, what would be non-Common-Lisp-style closures?

I understand that a "closure" is something which is typical of
functional programming languages. -- Scheme-style closures, for example.
I don't know Haskell, ML etc. but I do suspect that we could create
closures in those languages as well. Maybe someone more expert than me
can help?
