IBM Open Enterprise SDK for Python 3.10 is delivered to maintain a high level of currency with the releases from the Python open-source community. IBM Open Enterprise SDK for Python enables application developers to use one of the fastest-growing programming languages natively on the IBM z/OS platform. With the latest version of IBM Open Enterprise SDK for Python, IBM brings the benefits of the popular Python open-source language to help accelerate modernization on z/OS.
Open Enterprise SDK for Python 3.10 is a port of the open-source Python Software Foundation (PSF) community 3.10 release that includes additional z/OS-specific enhancements. What's new in Open Enterprise SDK for Python 3.10 Key features and enhancements from the Python community in Open Enterprise SDK for Python 3.10 include the following: - Structural pattern matching. A powerful feature that has been added to Python 3.10. It includes a match-case statement and enables you to perform match-case logic based on whether an object matches a given pattern. The feature can be particularly useful for data processing. - Parenthesized context managers. A result of Python's new PEG-based parser that was introduced in Python 3.9, with parenthesized context managers, you can now use parens to break up multiple statements across multiple lines. - New type union operator. Enables writing union types as x|y instead of union(x, y). The new union syntax is enabled in function, variable, and parameter annotations. This syntax is more generic and readable and is similar to the syntax of other languages. - Improved error messages. Python error messages are improved to provide more information to help resolve errors, including syntax errors. - New features in the Python Standard Library. Optional length-checking is added to the built-in zip. When enabled, a ValueError is raised when one of the arguments is exhausted before the others. - Enhanced line-number precision to improve diagnostic capabilities. Corrects an accuracy problem when providing source-code line numbers of the source, especially when debugging. To fix this intermittent problem, Python now uses a new method to determine the line number. This correction also fixes the same issue when using profiling and other coverage tools. IBM improvements to Open Enterprise SDK for Python 3.10 include the following: - Improvements in fork and multiprocessing usability on z/OS. This improves multiprocessing execution when using these functions in Open Enterprise SDK for Python 3.10. - Improved support for installing from wheels on z/OS. Fixes are implemented to improve encoding and file tagging when you use the Python wheel package to install a package on z/OS. - Fixes in scenarios in which Python performed auto-conversion on ttys.
