Pengelolaan Versi API dan ABI

CPython exposes its version number in the following macros. Note that these correspond to the version code is built with, not necessarily the version used at run time.

Lihat Stabilitas API C untuk diskusi tentang stabilitas API dan ABI di seluruh versi.

PY_MAJOR_VERSION

3 di 3.4.1a2.

PY_MINOR_VERSION

4 di 3.4.1a2.

PY_MICRO_VERSION

1 di 3.4.1a2.

PY_RELEASE_LEVEL

a di 3.4.1a2. Ini bisa berupa 0xA untuk versi alfa, 0xB untuk versi beta, 0xC untuk kandidat rilis atau 0xF untuk versi final.

PY_RELEASE_SERIAL

2 di 3.4.1a2. Nol untuk rilis final.

PY_VERSION_HEX

The Python version number encoded in a single integer.

The underlying version information can be found by treating it as a 32 bit number in the following manner:

Bytes	Bits (big endian order)	Meaning	Value for 3.4.1a2
1	1-8	PY_MAJOR_VERSION	0x03
2	9-16	PY_MINOR_VERSION	0x04
3	17-24	PY_MICRO_VERSION	0x01
4	25-28	PY_RELEASE_LEVEL	0xA
	29-32	PY_RELEASE_SERIAL	0x2

Thus 3.4.1a2 is hexversion 0x030401a2 and 3.10.0 is hexversion 0x030a00f0.

Use this for numeric comparisons, e.g. #if PY_VERSION_HEX >= ....

This version is also available via the symbol Py_Version.

const unsigned long Py_Version

Part of the Stable ABI since version 3.11.

The Python runtime version number encoded in a single constant integer, with the same format as the PY_VERSION_HEX macro. This contains the Python version used at run time.

Added in version 3.11.

All the given macros are defined in Include/patchlevel.h.
