python - How to use pprint to print an object using the built-in __str__(self) method? - Stack Overflow

Dan's solution is just wrong, and Ismail's in incomplete.

__str__() is not called, __repr__() is called.
__repr__() should return a string, as pformat does.
print normally indents only 1 character and tries to save lines. If you are trying to figure out structure, set the width low and indent high.

Here is an example

class S:
    def __repr__(self):
        from pprint import pformat
        return pformat(vars(self), indent=4, width=1)

a = S()
a.b = 'bee'
a.c = {'cats': ['blacky', 'tiger'], 'dogs': ['rex', 'king'] }
a.d = S()
a.d.more_c = a.c

print(a)

This prints

{   'b': 'bee',
    'c': {   'cats': [   'blacky',
                         'tiger'],
             'dogs': [   'rex',
                         'king']},
    'd': {   'more_c': {   'cats': [   'blacky',
                               'tiger'],
                  'dogs': [   'rex',
                              'king']}}}

Which is not perfect, but passable.

pprint.pprint doesn't return a string; it actually does the printing (by default to stdout, but you can specify an output stream). So when you write print record, record.__str__() gets called, which calls pprint, which returns None. str(None) is 'None', and that gets printed, which is why you see None.

You should use pprint.pformat instead. (Alternatively, you can pass a StringIO instance to pprint.)

October 18, 2022 - Think of dictionaries in Python to get an idea of the format for JSON – “key”/”value” pairs. The “keys” always being strings, the “values” include ints, Bools, arrays, none, and other objects. There are multiple ways to get data for this type of project – I found a JSON file on employees for a dummy company that I will use for this lesson. You can also use request from the urllib module to get mock data. Let’s get into some code and see pprint in action.
