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?

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
You've set your editor to display tabs as 4 spaces, but then you've
sometimes used tabs in your file, and sometimes 4 spaces. Look at how
your code is indented in your post: the addNode and addEdge definitions
are indented with tab characters instead of spaces, so Python thinks
they are eight spaces in. This makes them defined inside of __init__,
rather than as part of your class.
Set your editor to insert spaces when you use the Tab key, and set it to
use 4-space indents. Then find all the tab characters in your file and
replace them with the proper number of spaces.
