# Remoção pendente no Python 3.18

- As seguintes funções privadas estão descontinuado e planejadas para remoção no Python 3.18:

  - `_PyBytes_Join()`: use `PyBytes_Join()`.

  - `_PyDict_GetItemStringWithError()`: use `PyDict_GetItemStringRef()`.

  - `_PyDict_Pop()`: use `PyDict_Pop()`.

  - `_PyLong_Sign()`: use `PyLong_GetSign()`.

  - `_PyLong_FromDigits()` e `_PyLong_New()`: use `PyLongWriter_Create()`.

  - `_PyThreadState_UncheckedGet()`: use `PyThreadState_GetUnchecked()`.

  - `_PyUnicode_AsString()`: use `PyUnicode_AsUTF8()`.

  - `_PyUnicodeWriter_Init()`: substitua `_PyUnicodeWriter_Init(&writer)` por `writer = PyUnicodeWriter_Create(0)`.

  - `_PyUnicodeWriter_Finish()`: substitua `_PyUnicodeWriter_Finish(&writer)` por `PyUnicodeWriter_Finish(writer)`.

  - `_PyUnicodeWriter_Dealloc()`: substitua `_PyUnicodeWriter_Dealloc(&writer)` por `PyUnicodeWriter_Discard(writer)`.

  - `_PyUnicodeWriter_WriteChar()`: substituta `_PyUnicodeWriter_WriteChar(&writer, ch)` com `PyUnicodeWriter_WriteChar(writer, ch)`.

  - `_PyUnicodeWriter_WriteStr()`: substitua `_PyUnicodeWriter_WriteStr(&writer, str)` por `PyUnicodeWriter_WriteStr(writer, str)`.

  - `_PyUnicodeWriter_WriteSubstring()`: substitua `_PyUnicodeWriter_WriteSubstring(&writer, str, start, end)` por `PyUnicodeWriter_WriteSubstring(writer, str, start, end)`.

  - `_PyUnicodeWriter_WriteASCIIString()`: substitua `_PyUnicodeWriter_WriteASCIIString(&writer, str)` por `PyUnicodeWriter_WriteASCII(writer, str)`.

  - `_PyUnicodeWriter_WriteLatin1String()`: substitua `_PyUnicodeWriter_WriteLatin1String(&writer, str)` por `PyUnicodeWriter_WriteUTF8(writer, str)`.

  - `_PyUnicodeWriter_Prepare()`: (sem substituto).

  - `_PyUnicodeWriter_PrepareKind()`: (sem substituto).

  - `_Py_HashPointer()`: use `Py_HashPointer()`.

  - `_Py_fopen_obj()`: use `Py_fopen()`.

  O projeto pythoncapi-compat pode ser usado para obter essas novas funções públicas no Python 3.13 e versões anteriores. (Contribuição de Victor Stinner em gh-128863.)
