Python 3.14+platformfunction

platform.invalidate_caches()

system and machine

Clears the platform module's internal cache so that uname(), node() and others query the system again (3.14+).

Syntax

platform.invalidate_caches()

The module remembers answers from the first call, so if the hostname changes while the program runs (common for long-lived services and containers), node() keeps returning the old value. invalidate_caches() is the only supported way to see the new value without restarting. Before 3.14 there was no such way.

Examples

import platform
before = platform.uname()
print(platform.uname() is before)  # → True — ответ взят из кэша
platform.invalidate_caches()
print(platform.uname() is before)  # → False — система опрошена заново
