Take a look at the Packages documentation (Section 6.4).

In short, you need to put a blank file named

__init__.py

in the lib directory.

Create a subdirectory named lib.
Create an empty file named lib\__init__.py.
In lib\BoxTime.py, write a function foo() like this:
```
def foo():
    print "foo!"
```
In your client code in the directory above lib, write:
```
from lib import BoxTime
BoxTime.foo()
```
Run your client code. You will get:
```
foo!
```

Much later -- in linux, it would look like this:

% cd ~/tmp
% mkdir lib
% touch lib/__init__.py
% cat > lib/BoxTime.py << EOF
heredoc> def foo():
heredoc>     print "foo!"
heredoc> EOF
% tree lib
lib
├── BoxTime.py
└── __init__.py

0 directories, 2 files

Python 2.7.6 (default, Mar 22 2014, 22:59:56)

Type "help", "copyright", "credits" or "license" for more information.
>>> from lib import BoxTime
>>> BoxTime.foo()
foo!

You can try inserting it in sys.path:

sys.path.insert(0, './lib')
import BoxTime

ANSWER 4

Try import .lib.BoxTime. For more information read about relative import in PEP 328.
