A lot of issues:

•   str(weights)
    str(numberlist)
  

  does nothing

• You are only sorting ascendingly w.r.t the summation of digits, but not sorting them alphabetically in cases of same summations.

• The output should be a string of original element, separated by a space. Not the key-value pair of original element and its summation.

share code if you done it correctly please

already mentioned in kata title and task

return true if the walk the app gives you will take you exactly ten minutes

Comment is unclear and unhelpful.

i mean, the obvious thing to do would be to loop through the sum of the weight digits and order them by value and if you find any case where you have duplicate values, then order the duplicate values by their "original numbers" alphabetically. example:
"90" = 9 + 0 = 9. "180" = 1+8+0= 9. since both values(sum of the original weight) are 9,you sort them by their original weights instead of values, which is: "90 < 180" (in this case,is false because 90 is greater than 180 alphabetically. ) then swap their positions in the string or sort their positions how you deem fit.

keep at it! I love feeling dumb myself, that's how I know I'm learning something :)

Still: Thank you. :)

Thank you. :p
