Python pretty print dictionary of lists, abbreviate long lists

Question

I have a dictionary of lists and the lists are quite long. How can I print it in a way that only a few elements of the list show up? Obviously, I can write a custom function

You could use the pprint module:

pprint.pprint(obj)

Would output:

{'key_1': ['EG8XYD9FVN',
           'S2WARDCVAO',
           'J00YCU55DP',
           'R07BUIF2F7',
           'VGPS1JD0UM',
           'WL3TWSDP8E',
           'LD8QY7DMJ3',
           'J36U3Z9KOQ',
           'KU2FUGYB2U',
           'JF3RQ315BY'],
 'key_2': ['162LO154PM',
           '3ROAV881V2',
           'I4T79LP18J',
           'WBD36EM6QL',
           'DEIODVQU46',
           'KWSJA5WDKQ',
           'WX9SVRFO0G',
           '6UN63WU64G',
           '3Z89U7XM60',
           '167CYON6YN']}

And,

pprint.pprint(obj,depth=1)

Would output:

{'key_1': [...], 'key_2': [...]}

And,

pprint.pprint(obj,compact=True)

would output:

{'key_1': ['EG8XYD9FVN', 'S2WARDCVAO', 'J00YCU55DP', 'R07BUIF2F7',
           'VGPS1JD0UM', 'WL3TWSDP8E', 'LD8QY7DMJ3', 'J36U3Z9KOQ',
           'KU2FUGYB2U', 'JF3RQ315BY'],
 'key_2': ['162LO154PM', '3ROAV881V2', 'I4T79LP18J', 'WBD36EM6QL',
           'DEIODVQU46', 'KWSJA5WDKQ', 'WX9SVRFO0G', '6UN63WU64G',
           '3Z89U7XM60', '167CYON6YN']}
