Pandas UDF can be limited, so we can speed up the Pandas GroupBy-Apply pattern by using NumPy instead, resulting in a significant performance improvement. However, it's important to benchmark and consider costs before deciding between Pandas and NumPy for your specific use case... read more  

The author started programming in Rust and it influenced their approach to designing programs in Python. They emphasize the use of type hints, dataclasses for structured data, algebraic data types for explicit data shapes, and newtypes for specifying domain-specific usage of existing types. These pr.. read more  

A large number of PGP signatures on PyPI can’t be correlated to any well-known PGP key and, of the signatures that can be correlated, many are generated from weak keys or malformed certificates. The results suggest widespread misuse of GPG and other PGP implementations by Python packagers, with said.. read more
