pvlib

A personal “utility library” repo of lightweight, self-contained my* modules that mirror common Python libraries (for learning, experimentation, and quick bootstrapping), plus a few small test programs.

This repository is intentionally simple and modular, designed for:

• learning how common Python libraries work internally
• quickly validating Python environments
• bootstrapping scripts without pulling in large dependencies

Project Goals & Philosophy

The primary goal of pvlib is to serve as a personal, evolving repository of custom-built and commonly used Python libraries.

This project exists to:

• Re-implement and wrap familiar libraries
  Build simplified versions of popular tools (NumPy, Pandas, tqdm, etc.) to better understand their structure, patterns, and design decisions.
• Create a personal standard toolkit
  Maintain a trusted set of utilities that can be reused across many projects without starting from scratch.
• Enable rapid experimentation
  Quickly test ideas, environments, and scripts without relying on heavyweight dependencies or complex installs.
• Deepen Python mastery
  Reinforce fundamentals such as iteration, data handling, testing, system inspection, plotting, and I/O by implementing them directly.
• Act as a living learning log
  This repository is intentionally unfinished and evolving as new libraries are explored, rewritten, or extended.

This project is not intended to replace production-grade libraries. Instead, it prioritizes:

• clarity over completeness
• readability over performance
• understanding over abstraction

Included Modules

Current modules mirror familiar Python libraries (each one is intentionally minimal and readable):

• mynumpy/ – NumPy-style helpers and array utilities
• mypandas/ – Pandas-style helpers for basic data handling
• mytqdm/ – lightweight progress / iteration helpers
• myrequests/ – simple HTTP request wrappers
• mypsutil/ – system and resource inspection helpers
• mypytest/ – quick testing / validation helpers
• mycolorama/ – terminal color / formatting helpers
• mymatplotlib/ – plotting helper wrappers
• mybeautifulsoup/ – BeautifulSoup-style HTML parsing / scraping helpers (new)

Naming convention: modules are prefixed with my to make it obvious they’re educational/experimental re-implementations and not drop-in replacements.

Repo Layout

At the repo root you’ll find the modules plus a few helper/reference files:

• INSTALL.txt – install notes
• LIBRARIES.txt – dependency notes / library list
• install.sh – helper installer script
• test_libs.py – general smoke test for installed/importable libs
