Note

Python 3.8 is now the latest feature release series of Python 3. Get the latest release of 3.8.x here. We plan to continue to provide bugfix releases for 3.7.x until mid 2020 and security fixes until mid 2023.

Python 3.7.7rc1 is the release candidate preview of the seventh and most recent maintenance release of Python 3.7. The Python 3.7 series contains many new features and optimizations.

Note that 3.7.7rc1 is a release preview and thus its use is not recommended for production environments.

Please see What’s New In Python 3.7 for more information.

• There are now "web-based" installers for Windows platforms; the installer will download the needed software components at installation time.
• There are redistributable zip files containing the Windows builds, making it easy to redistribute Python as part of another software package. Please see the documentation regarding Embedded Distribution for more information.
