Questions tagged [winreg]

_winreg is the python module for Windows registry access. This module provides a low-level interface to the Windows registry database. The interface directly mirrors the underlying Windows API.

_winreg (renamed to winreg in Python 3) is the python module for Windows registry access. The functions in this module expose the Windows registry API to Python. Rather than using an integer as the registry handle, a handle object is used to ensure that the handles are closed correctly, even if the programmer neglects to explicitly close them.

For a complete reference, please see the python documentation at docs.python.org.
