Hello Friends,
I am working on this code but I kind of get the same error over and over again.
Could any of you help me fix this part of the error?
It's an indentation error: In the following the three function defs for
__init__, addNode and addEdge should all be at the same indentation
level. Instead, you have the later two defined *inside* the __init__.

File RW1:

AttributeError: PHY_NETWORK instance has no attribute 'addNode'
The error that it give back is as above. I have the classes defined in RW1 file
and I am importing the classes onto RW3 file and yet, It doesn't seem to work.
I really am in need of your valuable suggestions. Thank You
