Any way to properly pretty-print ordered dictionaries?

Question

I like the pprint module in Python. I use it a lot for testing and debugging. I frequently use the width option to make sure the output fits nicely within my terminal window

As of Python 3.8 : pprint.PrettyPrinter exposes the sort_dicts keyword parameter.

True by default, setting it to False will leave the dictionary unsorted.

>>> from pprint import PrettyPrinter

>>> x = {'John': 1,
>>>      'Mary': 2,
>>>      'Paul': 3,
>>>      'Lisa': 4,
>>>      }

>>> PrettyPrinter(sort_dicts=False).pprint(x)

Will output :

{'John': 1, 
 'Mary': 2, 
 'Paul': 3,
 'Lisa': 4}
