4. Example Codes Demonstrating the Use of sys.implementation

Python sys.implementation is a way of finding information about the implementation of a Python interpreter and its current execution in the process. The sys.implementation will not bear a different value during a run of the interpreter nor between implementation versions.

Syntax

sys.implementation

Parameters

Returns

The return type of this method is an object containing information about the Python implementation. The object’s information and length may vary on the attributes that Python implements on a platform.

However, the attributes mentioned below are required to exist in all Python implementations:

1. name - a string representing the implementation’s identifier, like cpython.
2. version - a named tuple that represents the version of the Python implementation. It displays information in the same format as sys.version_info.
3. hexversion - it represents the implementation version of Python language in hexadecimal format, like sys.hexversion.
4. cache_tag - a tag used by a system’s import machinery in the filenames of cached modules.

Example Codes Demonstrating the Use of sys.implementation

Use the sys.implementation on Windows OS

import sys

print(sys.implementation)

Output:

namespace(name='cpython', cache_tag='cpython-310', version=sys.version_info(major=3, minor=10, micro=5, releaselevel='final', serial=0), hexversion=50988528)

The above code may produce different results based on the user’s system and the Python implementation.

Use the sys.implementation on UNIX OS

import sys

print(sys.implementation)

Output:

namespace(_multiarch='x86_64-linux-gnu', cache_tag='cpython-38', hexversion=50858736, name='cpython', version=sys.version_info(major=3, minor=8, micro=10, releaselevel='final', serial=0))

If a virtual environment is in use, then python implementation might vary from the base OS.
