Python and Git guides covering dependencies, environments, change history and code examples with explanations and primary sources.
Choose the problem you need to solve: a Python environment, package imports or Git history. Check commands against your tool version and the conditions of your project.
Distinguish missing and empty settings, parse ports and booleans explicitly, and report configuration errors without exposing secrets.
Use ISO timestamp strings and decimal strings, then reconstruct the fields explicitly. A complete standard-library example shows timezone checks, precision and predictable failures.
Learn how to parse JSON data in Python from both string literals and files, and how to effectively handle potential decoding errors using the built-in json module.
Use a named logger, configure the application once, and attach safe context without duplicating every error.
A practical guide to using pathlib for file existence checks, extension manipulation, directory navigation, and path resolution without introducing platform-specific bugs on Windows or Unix systems.
Preserve shared history or replay local work before integration.
A guide to using the Python csv module to automatically detect delimiters, handle Unicode Byte Order Marks (BOM) with utf-8-sig, and manage platform-specific newline issues using the Sniffer class and correct file opening parameters.
How Python resolves relative paths depends on the process working directory, which varies by launcher. This guide shows how to inspect the working directory, choose and document an explicit path base, and understand why __file__ cannot always be trusted.
A small, repeatable setup for a project and a quick check that pip uses the right Python.
