Using this general structure:
setup.py
/package
__init__.py
project.py
/data
client.log
I have a script that saves a list of names to client.log, so I don't have to reinitialize that list each time I need access to it or run the module. Before I set up this structure with pkg_resources, I used open('.../data/client.log', 'w') to update the log with explicit paths, but this doesn't work anymore.
Is there any way to edit data files within modules? Or is there a better way to save this list?

You can write to a file in Python using the open() function. You must specify either “w” or “a” as a parameter to write to a file. “w” overwrites the existing content of a file. “a” appends content to a file.
Place the files that you want to include in the package directory (in our case, the data has to reside in the roman/ directory). Add the field include_package_data=True in setup.py. Add the field package_data={'': [... patterns for files you want to include, relative to package dir...]} in setup.py .
No, pkg_resources are for reading resources within a package. You can't use it to write log files, because it's the wrong place for log files. Your package directory should typically not be writeable by the user that loads the library. Also, your package may in fact be inside a ZIP-file.
You should instead store the logs in a log directory. Where to put that depends on a lot of things, the biggest issue is your operating system but also if it's system software or user software.
