Though the documentation tells when disassembling a class, it disassembles all methods for dis.dis, but staticmethod and classmethod are ignored. I don't know whether this is intended.I write to patch to add staticmethod and classmethod. But unfortunately when I write tests, one unrelated test fails and I cannot figure out why.

Though don't know why but simply replace %-4d with %3d in dis_bug708901 can fix the test. I updated the patch so all the tests pass and then I'll spend some time figuring out why.

After researching the code, I think changing ' %-4d' to '%3d' in dis_bug708901 is right. Since I added some some lines and the lineno of test_bug708901 has arrived at 100+ and the leading space should not be there. According to the code of dis.dis, the right format string should be '%3d'. Not only test_bug708901, all the other ' %-4d' should be changed to '%3d'. If we add 1000+ lines at the head of the file, then all the ' %-4d' format string will lead to test failures.I update my patch.

The code and test changes in the latest patch look good to me. For documentation, I suggest updatinghttps://docs.python.org/3/library/dis.html#dis.dis to:- say "it disassembles all methods (including class and static methods)" when describing how classes are handled.- add a version changed note for 3.6 to say that class and static methods are disassembled in addition to normal instance methods when disassembling a class

I update the documentation. Learning fromdevguide, the change of whatsnew is the committer's work. ;)

If this is new feature, perhaps the docs need the versionchanged directive. Otherwise the patch should be applied to all maintained branches.Added other comments on Rietveld.

Thanks for your comments Serhiy. I update the patch according to your comments.Actually I don't think this is a new feature. Maybe staticmethod and classmethod are just forgotten.As for separate tests for staticmethod and classmethod, I think they are not needed for this patch since right now we can use dis.dis to disassemble them explicitly. Only when dis.dis a class they are missing. But since there are no tests for them, adding tests for them is good.

LGTM.Nick, do you consider this as a new feature, or as a fix?

Looking at the history of the dis module, I'd now class this as a bug fix for 3.5+ - it looks like dis.dis gained the ability to disassemble static and class methods as a side-effect of the removal of bound methods in Python 3 (seehttps://hg.python.org/cpython/rev/48af6375207e ) but because it was a side effect, the additional changes needed to also handle them when disassembling a class were missed.
