## Code Before:
import os

class RunDir(object):
    def __init__(self, dir, create=False):
        self._run_dir = dir
        self._create = create

    def __enter__(self):

        os.chdir(self._starting_dir)


def open_run_dir(dir, **kwds):
    return RunDir(dir, **kwds)

## Instruction:
Rename dir variable to directory.
