Frequently Asked Questions
==========================

I'm importing functions from a Python module, but when I change the module, Bluelake doesn't see the changes
------------------------------------------------------------------------------------------------------------

Placing re-usable functions into your own Python modules can be a good way to share code between automation scripts. For instance, say you have the following two files::

    # --- script.py
    import bluelake
    import mymodule

    mymodule.say_hello()


    # --- mymodule.py
    def say_hello():
        print('Hello')

Running the script from Bluelake should work fine. However, if you now make a change in ``mymodule.py`` and run ``script.py`` again, you'll see that Bluelake keeps running the old version.

This is a known limitation of importing Python modules: they are not automatically refreshed if the module's source file changes. To work around this, you have two options:

1. Restart Bluelake.
2. Use the following code to import your module in ``script.py``::

    from importlib import reload
    import mymodule
    reload(mymodule)

    mymodule.say_hello()


For more information, see the Python documentation of `importlib`_.
