Pending removal in Python 3.15

• The PyImport_ImportModuleNoBlock(): Use PyImport_ImportModule() instead.

• PyWeakref_GetObject() and PyWeakref_GET_OBJECT(): Use PyWeakref_GetRef() instead. The pythoncapi-compat project can be used to get PyWeakref_GetRef() on Python 3.12 and older.

• PyUnicode_AsDecodedObject(): Use PyCodec_Decode() instead.

• PyUnicode_AsDecodedUnicode(): Use PyCodec_Decode() instead; Note that some codecs (for example, “base64”) may return a type other than str, such as bytes.

• PyUnicode_AsEncodedObject(): Use PyCodec_Encode() instead.

• PyUnicode_AsEncodedUnicode(): Use PyCodec_Encode() instead; Note that some codecs (for example, “base64”) may return a type other than bytes, such as str.

• Python initialization functions, deprecated in Python 3.13:

  • Py_GetPath(): Use PyConfig_Get("module_search_paths") (sys.path) instead.

  • Py_GetPrefix(): Use PyConfig_Get("base_prefix") (sys.base_prefix) instead. Use PyConfig_Get("prefix") (sys.prefix) if virtual environments need to be handled.

  • Py_GetExecPrefix(): Use PyConfig_Get("base_exec_prefix") (sys.base_exec_prefix) instead. Use PyConfig_Get("exec_prefix") (sys.exec_prefix) if virtual environments need to be handled.

  • Py_GetProgramFullPath(): Use PyConfig_Get("executable") (sys.executable) instead.

  • Py_GetProgramName(): Use PyConfig_Get("executable") (sys.executable) instead.

  • Py_GetPythonHome(): Use PyConfig_Get("home") or the PYTHONHOME environment variable instead.

  The pythoncapi-compat project can be used to get PyConfig_Get() on Python 3.13 and older.
