Combine reprlib and pprint in Python?

Can I have pretty printed data output as in pprint.pprint (new lines, indentation), but also shortened lists as in reprlib.repr at the same time?

An ugly hack seems to be pprint(eval(reprlib.repr(data))), but is there a better way?

Since Python 3.12, reprlib.Repr has an indent option, which you can use to pretty-print. No need for the pprint module.

>>> example = [1, 'spam', {'a': 2, 'b': 'spam eggs', 'c': {3: 4.5, 6: []}}, 'ham']
>>> from reprlib import Repr
>>> print(Repr(indent=4).repr(example))
[
    1,
    'spam',
    {
        'a': 2,
        'b': 'spam eggs',
        'c': {
            3: 4.5,
            6: [],
        },
    },
    'ham',
]
>>> print(Repr(indent=4, maxlevel=1).repr(example))
[
    1,
    'spam',
    {...},
    'ham',
]
>>>

You can change the way an object is printed by overriding the __repr__() method on its class.

Python will allow you to override the repr of any class, so use it with care.
