python devtools

Python's missing debug print command and other development tools.

For more information, see documentation.

Install

Just

pip install devtools

If you've got python 3.7+ and pip installed, you're good to go.

Usage

from devtools import debug

whatever = [1, 2, 3]
debug(whatever)

Outputs:

test.py:4 <module>:
    whatever: [1, 2, 3] (list)

That's only the tip of the iceberg, for example:

import numpy as np

data = {
    'foo': np.array(range(20)),
    'bar': {'apple', 'banana', 'carrot', 'grapefruit'},
    'spam': [{'a': i, 'b': (i for i in range(3))} for i in range(3)],
    'sentence': 'this is just a boring sentence.\n' * 4
}

debug(data)

outputs:

Usage without Import

devtools can be used without from devtools import debug if you add debug into __builtins__ in sitecustomize.py.

For instructions on adding debug to __builtins__, see the installation docs.
