    i think the latter is easier-to-read, so i use this code
    (by Peter Norvig)

    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).
