i think the latter is easier-to-read, so i use this code

This doesn't work well if your strings contain spaces:

Lprint(
    [
        ["Just", "three", "words"],
        ["Just", "three words"],
        ["Just three", "words"],
        ["Just three words"],
    ]
)

prints:

((Just three words) (Just three words) (Just three words) (Just three words))

Output is often a compromise between readability and precision.

def lispstr(exp):
           # "Convert a Python object back into a Lisp-readable string."
    if isinstance(exp, list):

This won't work for your example, since you have a list of tuples, not a
list of lists and a tuple is not an instance of a list.

        return '(' + ' '.join(map(lispstr, exp)) + ')'
    else:
        return str(exp)
 
def Lprint(x): print(lispstr(x))

I like to use pprint, but it's lacking support for user-defined types. I
should be able to add a method (maybe __pprint__?) to my classes which
handle proper formatting (with line breaks and indentation).
