sysconfig exposes how the active interpreter was installed and built. Build and diagnostic tools can inspect directories and variables without fixing Windows, Linux, or macOS paths in code.

Inspect interpreter paths

import sysconfig

paths = sysconfig.get_paths()
print(paths["stdlib"])
print(paths["purelib"])
print(sysconfig.get_platform())

Understand installation schemes

A scheme groups destinations such as stdlib, scripts, include, and data. The right values depend on the environment and installation. Query get_scheme_names() and get_preferred_scheme() instead of concatenating directories.

Handle build variables carefully

get_config_var() and get_config_vars() expose details needed by extensions and build systems. They describe the running interpreter and do not guarantee compatibility with another Python. Log only necessary keys and avoid exposing sensitive paths.

Keep learning

Continue with runtime identification with platform. The official Python documentation, accessed July 22, 2026, lists installation schemes, paths, and configuration variables.
