Jython 2.7是否兼容Python 3.6代码？哪款Jython适配Python 3.6？

Great question! Let's break this down clearly:

Jython 2.7是否兼容Python 3.6代码？ #

Short answer: No, it doesn't.

Jython 2.7 is a Java-based implementation of Python 2.7, meaning it strictly follows Python 2.7's syntax, standard library, and behavioral rules. Python 3.6 introduced a ton of breaking changes and new features that don't exist in Python 2.7, so code written for 3.6 will almost certainly fail on Jython 2.7. Some key incompatibilities include:

• Python 3 requires print() as a function, while Jython 2.7 still supports the old print statement syntax
• String handling is completely different: Python 3 uses Unicode strings by default, whereas Jython 2.7 uses byte-based str and separate unicode types
• Python 3.6 features like f-strings, async/await syntax, and dictionary literal improvements aren't supported at all in Jython 2.7
• Many standard library modules were renamed or restructured in Python 3 (e.g., urllib split into submodules, ConfigParser became configparser)

哪一版本的Jython与Python 3.6兼容？ #

Unfortunately, there is no stable, officially released Jython version that fully supports Python 3.6.

The Jython project has been working on a Python 3-compatible branch (Jython 3.x) for years, but development progress has been slow. What's more, the current focus of the Jython 3.x branch is aligning with newer Python 3 versions (like Python 3.9 and above), not targeting Python 3.6 specifically. Any pre-release builds of Jython 3.x might have partial support for some Python 3 features, but they're not reliable for production use with Python 3.6 code.

If you need to run Python 3 code on the Java platform, you might want to consider alternatives like:

• Trying the latest development builds of Jython 3.x (with the caveat that they're unstable and incomplete)
• Using other Java-Python interoperability tools like JPype or GraalVM's Python runtime
