the code form

if <boolean statement>:
  return true
else:
  return false

is an antipattern. instead use

return <boolean statement>

Happy to help! :)

That is correct. Because order of multiplication doesn't matter, the product of the sorted numbers is the same as the product of the unsorted.

You don't need to sort the values beforehand and you're not getting the last value sorted anyway (i<x.length-1 should be i<x.length).

Should probably add that any characters other than '|' or 'J' should be mapped to '...'. That really wasn't clear.

if test:
    return True
else:
    return False

This is an antipattern. Just do:

return test
