open uses the current working directory, which is available through
the os.getcwd() function in Python.
If you want to use a path relative to the current module, you can use
that module's __file__ attribute.
os.path.dirname(os.path.abspath(__file__))
will give you the absolute path to the directory with the current module in it.

So if you want to open the foo.txt file in the same directory as the
module, you use
os.path.join(os.path.dirname(__file__), 'foo.txt')
