Hello @rudradatta3,

  1. There are so many print statements which are unnecessary.
    Reason:
    Your output format should match with the output format given in the question.

  2. The logic for calculating the diameter w.r.t. the current node as root is wrong.

I have corrected your code:

Hope, this would help.
Give a like if you are satisfied.
