platform.architecture()

system and machine

Returns the bitness and linkage format of an executable, the interpreter by default: ('64bit', 'ELF').

Syntax

bits, linkage = platform.architecture(executable=sys.executable, bits='', linkage='')

It relies on the system file utility, and on macOS universal binaries it may report a bitness other than the one the code actually runs under. To check whether the running interpreter is 64-bit, sys.maxsize > 2**32 is more reliable. It says nothing about the OS: a 32-bit Python on 64-bit Windows answers '32bit'.

Examples

import platform, sys
print(platform.architecture())  # → ? например ('64bit', 'ELF') на Linux, ('64bit', 'WindowsPE') на Windows
print(type(platform.architecture()).__name__)  # → tuple
print(sys.maxsize > 2**32)  # → ? True у 64-битного интерпретатора — надёжнее architecture()
