  • Silly (maybe) question re imported module(s)

    From Grizzy Adams@21:1/5 to All on Fri May 19 07:44:12 2023
    Morning All

    I'm working through the tutorial and running / saving work that I wish to keep and build on, most times I can save and (re)import later with no difference to when typed in console or editor and run with F5 (which saves before it can run)


    But sometimes saved work (albeit small) when imported does not work any longer

    I assume I have missed something, any pointers to what/how/why please

    Looks like you are using IDLE? If so, it's possible that in the original
    case you had some values set from a previous run that were picked up but
    when you reimport later those values are missing. It would help if you
    can post any error messages since they should give clues(like name
    errors for example).

    Also describe how you are "importing" the modules. are you typing

    import mymodule

    at the interactive prompt or are you using the File->Open menu
    to load them into the editor? (It sounds like the latter)

    reimport is not 100% reliable, in simple cases it will work, but as your
    code gets more complex it can break.

    I rarely use reimport. Usually just exit python and start again.

    If you are working on scripts then just run them from the Terminal
    will work well with any need to use reimport.

    at the moment my code is very minimal, one saved piece is a nice one-liner that I kept because I wanted to remember syntax and how easy/elegant "some" things are in python, but if I import it it fails

    I rarely use reimport. Usually just exit python and start again.

    I may have confused this I use import to get my saved work, the "re" was to shoe it had been saved by the editor

    Yes


    From consol

    import cube
    cubes
    Traceback (most recent call last):
    File "<pyshell#1>", line 1, in <module>
    cubes
    NameError: name 'cubes' is not defined

    You imported cube but tried to use cubes. I'm guessing
    cubes is defined inside cube so you would need

    cube.cubes

    File->Open mymodule.module into the editor, then F5 to run all is well


    ================ RESTART: D:\Shades\Tools\Python\Temp\cube.py ================
    cubes
    [0, 1, 8, 27, 64, 125, 216, 343, 512, 729]


    cubes looks like it should be a function but in that case there
    should be parens after it. So I'm not sure how that is working!

    I'd expect that you need to do:

    import cube
    cube.cubes()

    Ah, now I understand. cubes is a literal list defined in the module.


    But that was spot on, thanks

    import cube
    cube.cubes
    [0, 1, 8, 27, 64, 125, 216, 343, 512, 729]

    Glad to help.
