PPrint Ordered Sets

The standard library pprint module, but with the feature that all sets are ordered.

Why does this package exist?

This package is a backport for the bug-fix bpo-27495. This package ensures that set and frozenset objects are always ordered, which is not true of the pprint module.

As of writing this, the pull request that fixes this bug has not been merged.

Example

>>> import pprint_ordered_sets as pprint
>>> obj = set("abcdefg")
>>> print(obj)  # Will be different on different systems.
{'d', 'f', 'b', 'g', 'e', 'a', 'c'}
>>> pprint.pp(obj)  # Will be same on all systems.
{'a', 'b', 'c', 'd', 'e', 'f', 'g'}

Testing

This package requires no dependencies to test, simply run:

python -m unittest test_pprint_ordered_sets.py
