Haven't figured out a way to do this, or if it's even really possible within MD, but can I create a python module and import it to use in another module?

   Do you mean when running via moneybot or when running the Python script within an extension mxt file?

   Do you really need an import, would an ‘exec’ do the job?

   Import requires the module to be in the current directory or in the path.. but I know there can be problems...

   What problems are you seeing?

   Hi, Thanks for the response...

   I'm just just talking about a plain script, not an mxt file. I've no experience with mxt files.

   On exec vs import...admittedly I've never used exec, but will look into that.

   On the import problem...for example i create a module with 1 function. I create another module to import the first module. I import the function and call the function. This works all fine outside of MD when I just run from the command line, but from MD I get:

   Beginning file D:\DataDrive\Jim\Documents\GitHub\moneydance\test-import.py at Tue May 11 19:37:00 MDT 2021
   Error running script: Traceback (most recent call last):
     File "D:\myfilepath\test-import.py", line 4, in <module>
       import testcsvread
   ImportError: No module named testcsvread
   Traceback (most recent call last):
     File "D:\DataDrive\Jim\Documents\GitHub\moneydance\test-import.py", line 4, in <module>
       import testcsvread
   ImportError: No module named testcsvread

   Thanks Stu.
   Since your last name I did more looking around and have figured out this also works:\

   import os
   path = os.path.dirname(os.path.abspath(__file__))

   import imp
   foo = imp.load_source('module.name', os.path.join(path,'testcsvread.py'))
   print (type(foo.readCSV))
   foo.readCSV()

   ----
   Any idea what pros/cons each method has?

   Thanks,
   Jim

   I think you know enough to read the docs and find out which method works best for you. I see you are relying on file. For example if you were running as an a extension, this variable is not set.

   Thanks for the tip Stu.

   I've not worked with extensions yet, but will keep that in mind.
