[Tutor] [EXTERNAL]Re: sum() function

[Olsen, Avalow Y]

Thanks, Alan!
I was typing it straight into the interpreter in Jupyter.  I restarted Jupyter and tried again. The problem went away.
By the way, there was no a sum variable in the previous assignments. The sum function didn’t work in my program. I created this snippet of test code to test the sum function.  And you know the rest of the story.

Thanks everyone for the help! This is such a supportive and enthusiastic community. I am proud to be part of it!

OK, That should not error in any version of Python.


How are you running the code?
Is it in a file?
Or are you typing it straight into the interpreter in Jupyter?


If the latter I'd restart Jupyter and try again.
I suspect it may be holding onto an old assignment of sum.


Other things to try:


print(sum([1,2,3,4,5,1,4,5]))

help(sum)


If its a file try running it in the vanilla python interpreter outside Jupyter.
