For nested lists....          impossible to improve   upon  P.Norvig's  code


def Lisprint(x):           print(lispstr(x))

def lispstr(exp):
    "Convert a Python object back into a Lisp-readable string."
    if isinstance(exp, list):
        return '(' + ' '.join(map(lispstr, exp)) + ')' 
    else:
        return str(exp)

a=    ' a b c '
x= a.split()
x +=  [['a', 'b', 'c']]
x +=  x

print(x) 
Lisprint(x) 

['a', 'b', 'c', ['a', 'b', 'c'], 'a', 'b', 'c', ['a', 'b', 'c']]

(a b c (a b c) a b c (a b c))


              ----------   Without the commas,   the visual difference 
(concision)  is  striking !
