Top PyPI Packages

Public

The most downloaded Python packages on PyPI, mapped to their GitHub repositories. This portfolio tracks the most critical packages in the Python ecosystem by download volume, spanning: - Cloud infrastructure (boto3, botocore, s3transfer) - Web and networking (requests, urllib3, certifi) - Data science and machine learning (numpy, pandas, scikit-learn, tensorflow) - Cryptography and security (cryptography, cffi, pyOpenSSL) - Developer tooling (setuptools, pip, wheel, packaging) - Core utilities (typing-extensions, six, python-dateutil) Together these packages form the backbone of Python's digital infrastructure, depended upon by millions of projects worldwide.
