# 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 C API Stability 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.
