os.name is defined as:
In my understanding, the value
'java'is for the benefit of jython, which is rather poorly. Other third-party implementations which may or may not have a "full os module" (e.g. ironpython) do not -- as far as I can tell -- get to be registered against this value, and Python 3.3's addition ofsys.implementationseems like a more reliable (and better supported) way to perform implementation-specific checks.Therefore I feel
os.name == 'java'only exists to confuse readers of the documentation, but doesn't really provide any value, and should be removed.masklinn commentedon Jan 21, 2022
PS: "platform.system()" also documents
Javaas a value which doesn't seem to make that much sense, however it's an open set so probably less of an issue / source of confusion.StanFromIreland commentedon May 3, 2025
