A short and sweet command line utility to find all names that have been imported with a universal (AKA wildcard) import and replace them with less dangerous import structures.
from numpy import * x = array()
import numpy x = numpy.array()
- This StackOverflow question, indicating there are people in this world eager to atone for the sins of their imports.
- Universal imports can make future maintenance nightmarish and impossible, as lots of people have complained in the past. They are not recommended by PEP8.
Hopefully, this tool can help mitigate some of the pain involved in identifying what's what and cleaning up code a little.
usage: universal-fixer.py [-h] [--replace] file_path Find all function names from universal imports and fix them! positional arguments: file_path Python file to find and replace universal imports in optional arguments: -h, --help show this help message and exit --replace Indicate you want to replace found matches to conform to PEP8 standard for wildcard import. Omitted, universal-fixer only searches and displays found matches, but does not alter the actual file.
Example output for
python universal-fixer.py test.py:
Found expression `abstractmethod` that belongs to module namespace `abc` in following contexts: Line 11: ...@abstractmethod Found expression `ABCMeta` that belongs to module namespace `abc` in following contexts: Line 9: ...re.replacegoobersmakr; x = ABCMeta(); wefzsegsergaewfsefsefsdfgs...

--replace, expect to be prompted before changing each import.
