.Python 3.11 available in RHEL 9 RHEL 9.2 introduces Python 3.11, provided by the new package `python3.11` and a suite of packages built for it, as well as the `ubi9/python-311` container image. Notable enhancements compared to the previously released Python 3.9 include: * Significantly improved performance. * Structural Pattern Matching using the new `match` keyword (similar to `switch` in other languages). * Improved error messages, for example, indicating unclosed parentheses or brackets. * Exact line numbers for debugging and other use cases. * Support for defining context managers across multiple lines by enclosing the definitions in parentheses. * Various new features related to type hints and the `typing` module, such as the new `X | Y` type union operator, variadic generics, and the new `Self` type. * Precise error locations in tracebacks pointing to the expression that caused the error. * A new `tomllib` standard library module which supports parsing TOML. * An ability to raise and handle multiple unrelated exceptions simultaneously using Exception Groups and the new `except*` syntax. Python 3.11 and packages built for it can be installed in parallel with Python 3.9 on the same system. To install packages from the `python3.11` stack, use, for example: [literal] ---- # dnf install python3.11 # dnf install python3.11-pip ---- To run the interpreter, use, for example: [literal] ---- $ python3.11 $ python3.11 -m pip --help ---- See link:https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/9/html/installing_and_using_dynamic_programming_languages/assembly_installing-and-using-python_installing-and-using-dynamic-programming-languages[Installing and using Python] for more information. Note that Python 3.11 will have a shorter life cycle than Python 3.9, which is the default Python implementation in RHEL 9; see link:https://access.redhat.com/support/policy/updates/rhel-app-streams-life-cycle[Red Hat Enterprise Linux Application Streams Life Cycle].
