Python Practice Workspace

A collection of Python practice scripts, experimental mini-projects, and algorithmic challenges, all managed as a unified uv workspace.

🧪 Experiment Scripts (TIL)

Small standalone scripts, each exploring one language feature or behavior:

Script	What it explores
000_infinite_recursion.py	What happens when recursion never terminates
001_python_asssert_statement.py	The assert statement
002_pass_by_value_or_reference.py	Whether Python passes arguments by value or reference
003_for_loops_vs_list_comprehensions.py	For loops vs. list comprehensions
004_text_wrap_module.py	The textwrap module
005_HTH_assessment_1.py	Practice assessment problem
006_HTH_assessment_2.py	Practice assessment problem
007_collections_counter.py	collections.Counter
008_class_attribute_default_values.py	Class attribute default values
009_python_match_case.py	Structural pattern matching (match/case)
010_object_attributes_by_value_or_reference.py	Whether object attributes are copied or referenced
011_python_requests_library.py	The requests library
012_inheritance.py	Class inheritance
013_python_asyncio.py	asyncio basics
014_scope_test_in_python.py	Scoping rules
015_linked_list.py	Implementing a singly-linked list

🚀 Mini-Projects

Each numbered folder is an independent workspace member with its own dependencies and README:

Project	Description
016-chapter_title_extractor/	Extracts chapter titles from a software engineering textbook's ToC using regex
017-email_finder/	Recursively crawls directories to extract unique email addresses
018-modules_and_packages/	Demonstrates Python module and package import mechanics
019-pillow_image_types_support/	Notebook exploring image format support in Pillow
020-text_counter/	Counts words/characters in text
021-token-generation-with-itsdangerous/	Secure token generation with the itsdangerous library

New mini-project folders use kebab-case (like 021-token-generation-with-itsdangerous).

📝 Coding Problems

coding-problems/ contains 149+ solutions organized by platform, with an auto-generated index linking every solution to its original problem. See its README.

⚙️ Setup & Usage

Run once in this directory to set up the shared environment (installs pytest too):

uv sync

Then:

uv run 013_python_asyncio.py                          # run a standalone script
uv run pytest                                         # run solution tests
uv run python coding-problems/generate_index.py       # regenerate the solutions index
uvx ruff check . && uvx ruff format --check .         # lint & format check (same as CI)

Workspace projects manage their own dependencies automatically:

cd 021-token-generation-with-itsdangerous
uv run itsdangerous_token_generation.py
