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,

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
