Make it easy to import the modules in parent directories

If you want to solve ValueError: attempted relative import beyond top-level package, DotDot may be helpful for you.

If it can be installed and imported successfully, it should work correctly.

Install via pip:

pip install dotdot

Consider a common project structure as following:

FooProject
    ├── foo
    │    ├── script.py
    │    └── util.py
    └── util.py

Now, script.py can import those utils by importing dotdot first. Like this:

import dotdot
import foo.util
import util

Moreover, you can import the modules in grandparent or even great grandparent directory by importing dotdotdot or dotdotdotdot first.

DotDot does this magic by changing sys.path[0] in import time.
