Python's missing debug print command and other development tools.
For more information, see documentation.
Just
pip install devtools[pygments]pygments is not required but if it's installed, output will be highlighted and easier to read.
devtools has no other required dependencies except python 3.6, 3.7, 3.8 or 3.9.
If you've got python 3.6+ and pip installed, you're good to go.
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:
modify /usr/lib/python3.8/sitecustomize.py making debug available in any python 3.8 code
# add devtools debug to builtins
try:
from devtools import debug
except ImportError:
pass
else:
__builtins__['debug'] = debug
