The Python Standard Library: Overview of Key Modules

One of Python's greatest strengths is its extensive Standard Library. This is a vast collection of modules that comes bundled with every Python installation, providing tools for a huge variety of common programming tasks. It's often referred to as Python's "batteries-included" philosophy.

Working with File Paths: The `os.path` Module

When we work with files, we often hardcode the file path as a simple string, like 'myfolder/myfile.txt'. This works, but it's not robust. What happens if your script is run on a different operating system? Windows uses a backslash (\) as a path separator, while macOS and Linux use a forward slash (/). Hardcoding paths with one type of slash can make your script fail on other systems.
