New submission from Steven D'Aprano <steve+pyt...@pearwood.info>:
Sorry Yashwanthbarad, this isn't a bug, you expect the wrong result. Augmented assignment for lists is documented to be the same as calling the extend method, which means your AppenedFuncShortHandOperator function modifies the argument list in-place. The AppenedFuncRegularAssignment simply replaces the *local variable* inside the function with a new list. Since it doesn't return the new list, the new list gets thrown away when the function returns, leaving the original list untouched. This is not a bug, it is the normal behaviour. If you need help understanding why it works the way it does, and the difference between mutating an object and binding a new object to a local variable, there are many places you can ask for help, such as Stackoverflow, the /learnpython sub-reddit on Reddit, the tutor mailing list and others. https://mail.python.org/mailman/listinfo/tutor Good luck! ---------- nosy: +steven.daprano resolution: -> not a bug stage: -> resolved status: open -> closed _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue41301> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
