How do I create a string containing the filepath of my python program?

We are creating a python program that executes specific macros within Polyworks based on user input into the program. Right now the code is:

roto.command.CommandExecute('MACRO EXEC("C:\\RotoWorks\\Macros\\CentrifugalCompressor")')

However this assumes that our program is always installed in C:\RotoWorks. Ideally, our app is portable. I'm sure theres a way to retrieve the filepath that Rotoworks is stored in, then just concatenate the rest of the filepath to the end. How do I do this?

You can retrieve the path from the __file__ attribute of the file. Use os.path.abspath on that attribute to retrieve the absolute path of the file and then os.path.dirname to retrieve the containing directory:

import os

file_directory = os.path.dirname(os.path.abspath(__file__))
path = os.path.join(file_directory, other_path) # join directory to an inner path
roto.command.CommandExecute('MACRO EXEC({})'.format(path))

Use os.path.dirname recursively to move out as many directories as you want.
