Hello! I don't see any error on your screenshot, can you elaborate, please?

i was expecting an error while executing d[1,2,3] as 1,2,3 should be given as tuple that is d[(1,2,3)]

That is an expected behaviour, parentheses are optional .

[amitesh-the-coder]

That is not an error, parentheses are optional .
ok sir understood thanks

Ah, sorry, I misunderstood you. Parentheses in tuple syntax is optional.

x = (1, 2, 3)
# or
x = 1, 2, 3

So, there's no bug.
