Guppy 3 (Guppy-PE for Python 3)

Guppy 3 is a comprehensive Python programming environment and heap analysis toolset, primarily serving as a port of the original Guppy-PE (Guppy-Python Environment) from Python 2 to Python 3. It provides robust tools for object and heap memory sizing, profiling, and analysis, essential for debugging memory-related issues and optimizing Python program performance. The library consists of subpackages like `heapy` for detailed heap introspection, `gsl` for a specification language, and `sets` for C-implemented bitsets and nodesets. The project maintains an active development status with regular minor releases.
