Python pprint with color syntax highlighting for the console

pprint_color.py

from pprint import pformat
from typing import Any

from pygments import highlight
from pygments.formatters import Terminal256Formatter
from pygments.lexers import PythonLexer


def pprint_color(obj: Any) -> None:
    """Pretty-print in color."""
    print(highlight(pformat(obj), PythonLexer(), Terminal256Formatter()), end="")

Thanks a bunch! Works well in Jupyter notebooks. (Extra parentheses needed for Python 3.)

Thanks for this!

Thanks!

Thanks!

Doesn't work for me in python 3.8 in a jupyter notebook

It doesn't work in newer versions because python no longer allows you to call print without parentheses. Just add parentheses to the last line and it will work:

    print( highlight(pformat(obj), PythonLexer(), Terminal256Formatter()) )

I've updated the gist for Python 3 and added type hints.

Thank you! I've added some more options and made color mode automatic per default:

import sys

from pprint import pformat, pprint
from typing import Literal, IO, Any

from pygments.formatter import Formatter
from pygments.formatters import get_formatter_by_name

    *,
    compact: bool = False,

    underscore_numbers: bool = False,
    color: Literal['auto', 'always', 'never'] = 'auto',

    if color == 'always' or (color == 'auto' and (stream or sys.stdout).isatty()):
        fmt = get_formatter_by_name(formatter) if isinstance(formatter, str) else formatter

        print(highlight(
