When to use Directory over Python Package? You can use “Python Package” when you want to put some modules in there which should be importable. PyCharm will automatically create an __init__.py for the directory. Why not create everything as a Python Package? Not every subdirectory in a project should necessarily be a package. For example … Read more
I had Python 3.10 and had the same error installing psutil from pip. I fixed the problem by installing an older version of pip using the command: pip install pip==21.3.1
Script vs. Module Here’s an explanation. The short version is that there is a big difference between directly running a Python file, and importing that file from somewhere else. Just knowing what directory a file is in does not determine what package Python thinks it is in. That depends, additionally, on how you load the … Read more
This is a somewhat controversial topic, and the answer for the moment is that there is no one single tool that everyone agrees is the “right way” to build source distributions, nor what that tool would be. You can see a long thread about it on the Python Packaging discourse. I hesitate to give too … Read more
Just use setuptools instead of distutils, it has find_packages exactly for that purpose: from setuptools import setup, find_packages setup( name=”myPackage”, packages=find_packages(), )
Quoting myself from here My current assumption is: […] you put your (mostly unpinned) dependencies to pyproject.toml instead of setup.py, so you library can be installed as a dependency of something else without causing much troubles because of issues resolving version constraints. On top of that, for “deployable applications” (for lack of a better term), … Read more
PyPi provides a JSON endpoint with package metadata: >>> import requests >>> url=”https://pypi.org/pypi/{}/json” >>> json = requests.get(url.format(‘pandas’)).json() >>> json[‘info’][‘requires_dist’] [‘numpy (>=1.9.0)’, ‘pytz (>=2011k)’, ‘python-dateutil (>=2.5.0)’] >>> json[‘info’][‘requires_python’] ‘>=2.7,!=3.0.*,!=3.1.*,!=3.2.*,!=3.3.*,!=3.4.*’ For a specific package version, add an additional version segment to the URL: https://pypi.org/pypi/pandas/0.22.0/json
I’d like to add a few notes on recent developments: PEP 518, first drafted in 2016, was marked as final in April of 2020. I’m interpreting it as an invitation to use pyproject.toml instead of setup.cfg. Quoting from the PEP: There are two issues with setup.cfg used by setuptools as a general format. One is … Read more

Store the absolute path to the module directory at the very beginning of the module: package_directory = os.path.dirname(os.path.abspath(__file__)) Afterwards, load your resources based on this package_directory: font_file = os.path.join(package_directory, ‘fonts’, ‘myfont.ttf’) And after all, do not modify of process-wide resources like the current working directory. There is never a real need to change the working … Read more
