While running /examples/client/client and /examples/repository/_simplerepo.py, encountered with errors because of the path issue with the tuf.

The following statements resolved the error.

import os

parent_dir = Path(__file__).resolve().parent.parent.parent
sys.path.append(str(parent_dir))

or it can be as follows.

import os

parent_dir = Path(__file__).resolve().parent[2]
sys.path.append(str(parent_dir))

The above can be updated in the actual code.
