Answer 1

Hi Prafful, I copied your example and it runs fine on my computer. Could you maybe try restarting the kernel and then running it again? Best, Eli

Answer 2

Hi Prafful! If you've set the two commands to be separate, like this:

Numbers = [1, 5, 64, 24.5]

and then you have

sum(Numbers)

in a separate code cell, please make sure to execute both of them in this order, from top to bottom. Hope this helps.
Best,
Martin
