PyPformat

Overview

PyPformat is a simple and highly customizable python pretty-formatting package designed as an alternative to the built-in pprint library - PyPformat uses a different, more natural formatting style and provides extensive personalization capabilities, including text colorizing or customized indentation marking, on top of the basic options like compact printing.

The example below demostrates the difference in the default outputs produced by the pprint and PyPformat libraries.

>>> from pprint import pprint
>>> import pformat as pf
>>>
>>> from collections import ChainMap, Counter, OrderedDict, UserDict, defaultdict
>>>
>>> mapping = {
...     "key1": 1,
...     "key2": OrderedDict({"key3": 3, "key4": 4}),
...     "key5": defaultdict(
...         str,
...         {
...             "key6": 6,
...             "a_very_long_dictionary_key7": ChainMap(
...                 {"key10": [10, 11, 12, 13], "key8": 8, "key9": 9}
...             ),
...             "key11": Counter("Hello"),
...         },
...     ),
...     "key12": UserDict({0: "a", 1: "b", 2: "c"}),
... }
>>>
>>> pprint(mapping)

                                                                         12,
                                                                         13],

Important

• The minimum (tested) python version required to use the PyPformat package is 3.9.
• The complete functionality of the PyPformat package (including all format configuration options) is described in the PyPformat - Usage document.
• While the PyPformat package is already quite versatile and customizable, its development is ongoing. A detailed list of the planned features/improvements can be found in the PyPformat - TODO document.

Installation

The PyPformat package can be installed via pip:

pip install pypformat

For developers

The PyPformat - Dev notes document contains the information about project development, testing and formatting.

Licence

The PyPformat project is licenced under the MIT Licence, which can be inspected in the LICENCE file in the project's root directory.
