Fix Python – Access data in package subdirectory [duplicate]


Asked By – Jacob Lyles

I am writing a python package with modules that need to open data files in a ./data/ subdirectory. Right now I have the paths to the files hardcoded into my classes and functions. I would like to write more robust code that can access the subdirectory regardless of where it is installed on the user’s system.

I’ve tried a variety of methods, but so far I have had no luck. It seems that most of the “current directory” commands return the directory of the system’s python interpreter, and not the directory of the module.

This seems like it ought to be a trivial, common problem. Yet I can’t seem to figure it out. Part of the problem is that my data files are not .py files, so I can’t use import functions and the like.

Any suggestions?

Right now my package directory looks like:


I am trying to access data.txt from module*.py!

Now we will see solution for issue: Access data in package subdirectory [duplicate]


You can use __file__ to get the path to the package, like this:

import os
this_dir, this_filename = os.path.split(__file__)
DATA_PATH = os.path.join(this_dir, "data", "data.txt")
print open(DATA_PATH).read()
