I have following directory structure:
A
|
|--B--Hello.py
|
|--C--Message.py
Now if the path of root directory A is not fixed, how can i import "Hello.py" from B to "Message.py" in C.

At first I suggest to add empty __init__.py file into every directory with python sources. It will prevent many issues with imports because this is how the packages work in Python:
In your case it this should look like this:
A
├── B
│ ├── Hello.py
│ └── __init__.py
├── C
│ ├── Message.py
│ └── __init__.py
└── __init__.py
Let's say the Hello.py contains the function foo:
def foo():
return 'bar'
and the Message.py tries to use it:
from ..B.Hello import foo
print(foo())
The first way to make it work is to let the Python interpreter to do his job and to handle package constructing:
~ $ python -m A.C.Message
Another option is to add your Hello.py file into list of known sources with the following code:
# Message.py file
import sys, os
sys.path.insert(0, os.path.abspath('..'))
from B.Hello import foo
print(foo())
In this case you can execute it with
~/A/C $ python Message.py
