API と ABI のバージョニング¶
Build-time version constants¶
CPython exposes its version number in the following macros.
Note that these correspond to the version code is built with.
See Py_Version for the version used at run time.
バージョン間の API と ABI の安定性については C API の安定性 を参照してください。
-
PY_MAJOR_VERSION¶
3.4.1a2の3。
-
PY_MINOR_VERSION¶
3.4.1a2の4。
-
PY_MICRO_VERSION¶
3.4.1a2の1。
-
PY_RELEASE_LEVEL¶
3.4.1a2のa。アルファでは0xA、ベータでは0xB、リリース候補では0xC、最終版では0xFとなります。
-
PY_RELEASE_SERIAL¶
3.4.1a2の2。最終リリースでは 0 になります。
-
PY_VERSION_HEX¶
The Python version number encoded in a single integer. See
Py_PACK_FULL_VERSION()for the encoding details.Use this for numeric comparisons, for example,
#if PY_VERSION_HEX >= ....
Run-time version¶
-
const unsigned long Py_Version¶
- 次に属します: Stable ABI (バージョン 3.11 より).
The Python runtime version number encoded in a single constant integer. See
Py_PACK_FULL_VERSION()for the encoding details. This contains the Python version used at run time.Use this for numeric comparisons, for example,
if (Py_Version >= ...).Added in version 3.11.
Bit-packing macros¶
-
uint32_t Py_PACK_FULL_VERSION(int major, int minor, int micro, int release_level, int release_serial)¶
- 次に属します: Stable ABI (バージョン 3.14 より).
Return the given version, encoded as a single 32-bit integer with the following structure:
Argument
No. of bits
Bit mask
Bit shift

#ifndef Py_PACK_FULL_VERSION #define Py_PACK_FULL_VERSION(X, Y, Z, LEVEL, SERIAL) ( \ (((X) & 0xff) << 24) | \ (((Y) & 0xff) << 16) | \ (((Z) & 0xff) << 8) | \ (((LEVEL) & 0xf) << 4) | \ (((SERIAL) & 0xf) << 0)) #endif
Py_PACK_FULL_VERSIONis primarily a macro, intended for use in#ifdirectives, but it is also available as an exported function.Added in version 3.14.
-
uint32_t Py_PACK_VERSION(int major, int minor)¶
- 次に属します: Stable ABI (バージョン 3.14 より).
Equivalent to
Py_PACK_FULL_VERSION(major, minor, 0, 0, 0). The result does not correspond to any Python release, but is useful in numeric comparisons.Added in version 3.14.
