The Python standard library

Python includes a rich set of built-in modules. The standard library provides tools for working with files, time, randomness, and error handling.

• The file system — Managing paths, files, and directories.
• Dates, times, and durations — Representing and comparing time values.
• Identifiers and randomness — Generating unique IDs and random numbers.
• Handling errors with exceptions — Catching and managing runtime errors.
