Can anyone show me what the hell with help()??? RRS feed

  • Question

  • when the help() in python 2.7 ,it does good,but in python 3.6.1 ,it shows nothing。

    Python 3.6 (64-bit)
    >> help(list)

    >>>

    Python 2.7 (64-bit)

    >>> help(list)
    Help on class list in module __builtin__:

  • Hi aeophie,

    It would be not the VS debugger or profiler tool issue, since python has his own supported forum, if possible, you could discuss this issue in the python forum:

    https://python-forum.io/
